Coldfusion site stopped working after updating JRE1.6->JRE1.7

I am getting
"Information","localhost-startStop-1","04/09/15","10:13:36",,"ColdFusion started"
"Error","localhost-startStop-2","04/09/15","10:13:48",,"The Cron service is not available. This exception is usually caused by service startup failure. Check your server configuration."
after updating from x64 JRE1.6 to x64 JRE1.7u25
My neo-cron.xml isn't damaged and all works hen I switch back to 1.6
I'm on Coldfusion 9,0,1,274733 Enterprise
Any ideas?

Patch your system up-to-date using the Unofficial Updater and it should work again:

Selenium-Standalone-Server will not work on Firefox and remains blank

I am using selenium-server-standalone-2.41.0.jar on Mac OSX 10.8.5 with Java 7 Update 55.
Everything works fine with Firefox up to version 25.0.1 but if I try v26, v27, v28 or v29 of Firefox, then my code will open up firefox and it will just hang (nothing loads on firefox screen).
When I downgrade Firefox back to v25 then it all starts working again fine.
Any thoughts or suggestions?
Thanks
EDIT: Posted problem on Selenium bug forum as well:
https://code.google.com/p/selenium/issues/detail?id=7279

There actually quite a few other threads on people having this same issue with Firefox starting up and a blank screen just sitting there doing nothing. I tried all combinations of Firefox from v25.0.1 to v33 with all versions of selenium-server-standalone from v2.41.0 to v2.44.0 and the only combination I can get to work is FF v25.0.1 with SSS v2.41.0.
So I finally came up with a workaround for this problem so I can use FF v33 for normal surfing and keep Selenium working with FF v25. This is what I did:
(1) I updated my day to day Firefox to the newest version.
(2) I downloaded a second older version of Firefox (v25.0.1) from here https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/25.0.1/ Then on my Mac I installed onto the Desktop and then renamed the it from Firefox.app to Firefox25.0.1.app and then moved it into my Applications folder.
(3) I created a new second profile for Firefox from here https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles and named it ffSeleniumProfile
(4) I then had to make sure the config file still had the default profile as the default. On Mac, look in ~/Library/Application Support/Firefox/profiles.ini file and it should look something like this (note that Default=1 should be under Profile0 )
[General]
StartWithLastProfile=1
[Profile0]
Name=default
IsRelative=1
Path=Profiles/abcd1234.default
Default=1
[Profile1]
Name=ffSeleniumProfile
IsRelative=1
Path=Profiles/a1b2c3d4.ffSeleniumProfile
(5) For Selenium Server Standalone, make sure you are using v2.41.0 selenium-server-standalone-2.41.0.jar from here http://selenium-release.storage.googleapis.com/2.41/selenium-server-standalone-2.41.0.jar
(6) Finally when you are starting Java and calling for Firefox/FirefoxDriver you will need to specify it to use Firefox25.0.1.app and the ffSeleniumProfile. I did this by adding the following System.setProperty to my main method of the primary java file that I use when starting java:
public static void main(String[] args)
throws InterruptedException,MalformedURLException {
System.setProperty("webdriver.firefox.bin", "/Applications/Firefox25.0.1.app/Contents/MacOS/firefox-bin");
System.setProperty("webdriver.firefox.profile", "ffSeleniumProfile");
}
Now when I start Selenium Java, it will use v25.0.1 of firefox along with the second profile, and when I just start firefox from my desktop it will use the default profile and whatever the newest version I have upgraded too.
Again this is a workaround only, but it solves my problem for now.

Hey Try Disabling some Add-ons in your Firefox browser one by one and try running the code This helped me on windows . Try it once..

What is libmuxer library ? If I run my server or application then I find these

"...this indicates that the Native Libraries are not properly being picked up the Weblogic server. This happens when the weblogic installed as 32 Bit on a 64 Bit Operating System or vice versa. In such scenario we need to explicitly specify the path to the Native Library."
Add the following to the setDomainEnv.sh
-Djava.library.path=/opt/bea/wlserver_10.3/server/native/solaris/sparc64/
Enable "Native IO" check box under each servers Tuning Tab.
Restart the servers.

I have the some problem, and thanks to sᴜʀᴇsʜ-ᴀᴛᴛᴀ for the hint! It looks like a 32bit/64bit issue. By the way, I'm using WebLogic 12 on a 64bit Centos5.
Note that the libmuxer.so is provided with weblogic for many archs, in fact
$ find $MW_HOME -name *muxer*
/application/weblogic/wlserver/server/native/macosx/libmuxer.jnilib
/application/weblogic/wlserver/server/native/linux/s390/libmuxer.so

/application/weblogic/wlserver/server/native/linux/i686/libmuxer.so
/application/weblogic/wlserver/server/native/linux/s390x/libmuxer.so
I edited the file $MW_HOME/wlserver/common/bin/commEnv.sh, where I found
#JAVA_USE_64BIT, true if JVM uses 64 bit operations
JAVA_USE_64BIT=false
and updated with
#JAVA_USE_64BIT, true if JVM uses 64 bit operations
JAVA_USE_64BIT=true
This worked for me, the Error you reported is gone.
Good luck!

JavaFx application in web browser : Jar working but JNLP / HTML doesn't

I have a javafx application, i am using netbeans as IDE. If i use the configuration stand alone the program is working without any trouble. But if i choose Run in browser i have a Runtime Error and the strack trace is pretty much empty :

If i try to deploy it, the JAR is working, but JNLP/HTML are leading to the same Runtime error.
I don't know where i must search because this runtime error doesn't give me a lot of information.
I have tried :
different browsers
Update/reinstall plugin/jre/jdk
I have found lot of topic about it, but most of them got Classnotfound exception where it seems my problem isn't the same because i never got it in the stacktrace.

Can anybody determine where the problem is? I also had problems trying to create a GWT app and a Python App Engine project.

Possible duplicate of: DevServer fails after updating to java 6u31
However, this problem seems to be documented (with solution) here:
http://code.google.com/p/googleappengine/issues/detail?id=6928
From the site:
Workaround - start the GAE with the following JVM parameter:
-Dappengine.user.timezone=UTC
(with eclipse, go to "run configuration", under the "Arguments" tab add "-Dappengine.user.timezone=UTC" to the VM arguments line. With maven-gae-plugin, add -Dappengine.user.timezone=UTC to the plugin configuration).
Good luck, and hopefully Google will support JDK u31 soon enough.
