I'm working with GuideWire - it's an out of box online insurance implementation. It's java based and has its own IDE. Firstly DCEVM worked perfectly, increasing my productivity dramatically. But couple days ago, it has stopped working, supplying me with
"Classes hasn't been reloaded as coderedefenition is disabled".
I've already tried everything and asked everybody for help, but nobody has faced this problem.
More than likely this is because the version of java you have started the app server with is now different and doesn't have the DCEVM applied to it.
You need to double click and run the applicable dcevm.jar and then it will throw up a UI for you to view and select the appropriate JDK's to apply the Dynamic Code Evolution VM changes onto.

I've attached two images to quickly display what I'm talking about.
It seems to effect my environment in incredibly annoying ways, such as no auto-complete for things like variables (every time I want to utilize a variable or parameter I have to literally type is every single time).
I tried restarting VSC, as well as uninstalling and reinstalling plugins. I also did a chkdsk for errors and corrected them but that seemed to have no correlation to the issues I've been having.
Interestingly enough I've also been having some other issues with my computer, such as my mail app not working anymore (it throws an error code), and not being able to connect to other microsoft products. Not sure if it's related but it seems to have began around the same time.
Reinstall the Java extension or update to a pre-release version.
Press CTRL + SHIFT + P, and type Java: Clean Java Language Server Workspace. to clean up the workspace and restart vscode.
I have one program, I maintain, that was originally written in Oracle Forms 6i. A while ago I migrated it to 11g. Our users access this Oracle Forms program through their Internet Explorer browser on their Windows 7 machines.
The problem has been that the program only seems to run well for our users, when they have Java 6 Update 45, installed on their machines. Going to a newer version causes problems.
Today, I wanted to get this resolved, so I updated my PC to Java 8.31, and attempted to access my Oracle forms program using IE. (Thanks to Viewing oracle app and getting: java.lang.ClassNotFoundException: oracle.forms.engine.Main I was able to get the form running again in my web browser.)
When my form ran, I found the tab key wouldn't advance to the next field on the login dialogue box. But after I logged in the tab key worked. (The tab key initially not working is a small thing, but it has really annoyed some of our users.)
I then used several different forms. Some worked just fine, no problems. But then when I clicked a button, on one form, it would endlessly try to complete a request; to the point that I couldn't even close the web browser to stop it. (Finally I just used task manager to end my web browser’s process.) This seemed to go in line with what some of our users have reported: (when attempting to use the latest Java) that the Oracle forms application just stops working completely after a while.
Because of these issues our users want to keep Java 6 Update 45 on their machines. I know this is a major security hole, but I haven’t quite nailed down what the solution to it is.
Has anyone else had a similar issue? We're running Oracle Fusion Middleware 11; specifically Forms Services version 11.1.2.0.0
Thanks.
Well this may not be a question that needs answering after all.
I've done some more testing since asking this. Besides the login dialogue box (not responding, as it should, to the tab key) everything else works just as it should.
I still have one form that hangs; but that’s all (and it may be caused by something else). All my other forms seem to work just fine.
I talked with one of my co-workers, and I realized we really need to investigate and determine what version of Java our users really are using. They may not have used the most recent version of Java; which I used with success, today. Or some may be already on it; and that's why they aren't complaining.
At any rate more research, is needed on my part. Thanks to all who read this. If any of you have had similar experience in something like this, still feel welcome to answer/comment.
I have a number of users who complain of a problem with an applet what I wrote. Mostly it works fine then one day it stops working. Checking the settings shows that no Java plugin is available. Once the plugin is reenabled and the browser restarted then the applet works again. I have also observed that the settings show that no plugin is enabled but following a browser restart the plugin is reenabled (without intervention of any kind) and the applet works.
Anyone have ideas how the plugin might get disabled? This has also happened to me so I can be fairly sure that the users aren't fiddling with their settings.
The installations are a mix of IE7/8 and Java 1.5/1.6.
UPDATE
I'm not 100% sure about this but it seems to me that the problem occurs when another applet is running. Many users have IBM HOD and I'm wondering if there could be some kind of clash
I'm having a strange bug wich i suspect to be specific to either MacOS X Lion and/or Java VM implementation on this OS.
When a java app summons a secondary window like a dialog box, i'm often unable to interact with its content ie. click, use menus, etc.
At first i though my app was buggy but since i had developped it on windows (where it worked fine) and switched to mac. I though some weird swing setting was to blame and i had noticed on the console that a compatibility mode with cocoa was enabled when i launched my app.
But i encountered the same bug with eclipse itself (a well known java based ide) tough it does not always happen in it while it's all the time with my app.
I have browsed for this issue but found nothing. Meanwhile i found that there is an issue between oracle and apple about java. I downladed a java update specific to Lion but the bug is still here
My question is : have you encountered the same bug ? is it macos lion specific ? have you found a workaround ??
Thanks
Made some research. Eclipse seems to be the cause of the bug. More precisely SWT support in eclipse under MacOS environnement.
The bug is not present with netbeans.
Short Story: My house was broken into MacBook Pro among stolen items. Bought a new MacBook restored from TimeMachine drive including Eclipse folder. System files could not be restored because hardware was slightly different. I did a system update and updated to 10.6.5 and Java 1.6.0_22, all the latest. I run Eclipse Helios for Java development for college assignments.
The problem I am having is that when I run Eclipse and start coding when I get to a method of any type when eclipse usually throws up an auto-complete type box underneath the current line the program hangs for a few seconds while it loads / moves through the list depending on how fast I am typing. Example:
JTextField txt = new JTextField();
txt.get....
I could type the second line out pretty quickly as I know what I am looking for but the program will hang (multicolor swirly mac icon will replace pointer). Eclipse process will spike to 100% and I will not be able to do anything until the auto-complete box finishes whatever it could possibly be doing and the suggestion moves down to "getText()" or whatever the list beginning with "get" contains.
Things I have done to correct include, re-downloading and installing eclipse into another location, creating a new workplace in that eclipse install, re-creating the projects and code files by hand (i.e. not importing anything). The problem still persist.
I am not seasoned enough in Java to abandon the helpful suggestion box, especially when I am learning new things.
Anyone else experience this problem or know a possible solution I have not tried?
This happens with me with Android development, and I have a clue as to why - documentation! If I uninstalled the documentation, meaning the completion list wouldn't show me any API documentation, the completion list was back up to normal speed. Installed it back, the completion list is slow again. This wasn't a problem in Galileo, just Helio.
I'm trying to find the best JVM settings to use with eclipse to see if I can improve things.
