I am creating a game with JavaFX with a team. Everything is going fine, except for one thing. We have created an automated GUI test, which we got to run on travis by running an Xvfb display:
before_install:
- export DISPLAY=:99.0
- sh -e /etc/init.d/xvfb start
- "/sbin/start-stop-daemon --start --quiet --pidfile /tmp/custom_xvfb_99.pid --make-pidfile --background --exec /usr/bin/Xvfb -- :99 -ac -screen 0 1280x1024x16"
However, this display does not support 3D. In the Travis log, there are literally thousands of lines saying the following:
WARNING: System can't support ConditionalFeature.SCENE3D
Sep 15, 2015 11:16:00 AM javafx.scene.shape.Shape3D <init>
Having thousands of warnings spammed in the log doesn't affect any of our tests. But when we added a bunch more objects, Travis cut off our build because the log file was getting too long:
WARNING: System can't support ConditionalFeature.SCENE3D
Sep 15, 2015 11:16:00 AM javafx.scene.shape.Shape3D <init>
The log length has exceeded the limit of 4 Megabytes (this usually means that test suite is raising the same exception over and over).
The build has been terminated.
Question: Does anyone know a way to support 3D on these kind of headless GUI tests?
Alternative: How to turn off these Warnings so that the log file won't become this long?
If more information is needed to answer this question, please ask! :)
One way could be to make sure (either in your code or in your test) that only that code is executed that is supported:
http://docs.oracle.com/javase/8/javafx/api/javafx/application/Platform.html#isSupported-javafx.application.ConditionalFeature-

I dug around option and source code but still unsure how to debug a bazel build, java specifically.
Also anyone know how I can change bazel, build it locally and use it on builds to verify. I found bazel invocation:
exec -a "$0" "${BAZEL_REAL}" "$#"
where BAZEL_REAL is a binary: /usr/local/Cellar/bazel/0.15.2/libexec/bin/bazel-real
But this doesn't explain closely how it starts and how I can debug it...
Like is it possible to jump in and debug com.google.devtools.build.lib.bazel.rules.java.BazelJavaLibraryRule while building my code? Like if I build my code with Maven, I can do mvnDebug.
bazel build -s
➜ bazel git:(master) ✗ bazel build //examples/java-native/src/main/java/com/example/myproject:hello-world -s
BAZEL_REAL==/usr/local/Cellar/bazel/0.15.2/libexec/bin/bazel-real

nevermind me, https://www.bazel.build/contributing.html#setting-up-your-coding-environment has the info I need.
Basically for starter
bazel --host_jvm_debug build //:*
the order of args are significant. For example below will NOT work
bazel build //:* --host_jvm_debug
To debug worker's jvm, get the command with bazel build -s, then append the remote debug startup opts.
Nothing happens after clicking on the web element. I have even print the statement after the click operation which is executed correctly but after that is is failing as click operation is not changing the object state.
Steps to reproduce -
create a selenium script to load google home page.
click on the I'm feeling Lucky button`enter code here.
it should load the doodle page.
When I run this script on my local machine, it worked fine. Now i have created an executable jar file using maven and eclipse to run my test suit and downloaded this jar on my remote desktop machine on server with all the necessary dependent files.
When I run the test using CMD java -jar "test-suit.jar".
It is opening IE browser successfully and load the url . It is clicking on I'm feeling lucky but it does not load doodle page after click and test fails . no error is given just i got this log:
log4j:WARN No appenders could be found for logger (org.apache.http.client.protoc
ol.RequestAddCookies).

I don't understand what could be the error. Whether it is not clicking and not throwing any error also or I need to take certain additional settings to be set on my server machine or change in my script to get it work.
I am facing issue while installing any of the Jenkins plugins suggested.
Actually after downloading,Jenkins.war file(which is latest 2.141) when i tried to execute the jar with
java -jar jenkins.war so it gave me an error of Jenkins require java 8 but you are using 10. Also,it says that java class version 54.0 is running,but it requires java 52.0.
But I was able to resolve this issue by setting --enable-future-java flag.
java -jar jenkins.war --enable-future-java flag
Now,after writing this command,jenkins is up and running but i am unable to install the plugins.
Also,im cmd prompt after the Jenkins is upa d running.There is one error also.
PFB :-

You need to add a flag which allows starting Jenkins with unsupported Java versions. You can do some google research on this.
If we change the Jenkins war file version from 2.141 to 2.814 then it is suitable with Java 10 and works fine for plugins installation of Jenkins
i had the /var disk full on my debian server and neo4j stopped as expected. I freed up the space on the disk but the neo4j server does not start throwing the error given below in the logs. I don't have any java or neo4j process running on the server that i may kill.
Things were stable with my neo4j setup for the past 6 months with around 1000 nodes. I am little novice on the java side so please let me know if i have missed out on anything basic.

I am using an openjdk 1.7 runtime environment which i think i should upgrade but i don't understand what is the cause of the error since everything was working fine before. Thanks for any help!
You should never ever manually modify anything inside the graph.db directory unless you're 100% sure what you're doing.
To prevent the datastore directory from continuously growing check your setting for keep_logical_logs in neo4j.properties, see http://docs.neo4j.org/chunked/stable/configuration-logical-logs.html.
Unless you require logical logs for online backup or cluster synchronization, you might be save deleting nioneo_logical.log.v* files. Make sure to have a backup first!
Also check your settings for open file limits, http://docs.neo4j.org/chunked/stable/linux-performance-guide.html#_setting_the_number_of_open_files.
There used to be a outdated version of Neo4j having a bug that might corrupt your datastore when running out of disc space. If that has happened to you either need to manually fix it on a binary level (which requires a lot of knowledge on Neo4j internals) or restore a previous backup from a time before you run out of disc.
I'm embarrassed to have to ask this, but I can't for the life of me figure out what I'm doing wrong.
I've downloaded the appengine-java-sdk-1.4.2 via the eclipse 3.6 plugin as per the instructions on Installing the Java SDK page. I am running Mac OSX 10.5.8 with JRE version 1.5.0_26. I have made the dev_appserver.sh file executable (chmod u+x dev_appserver.sh) and when I attempt to start the app server with one of the demos via the command
bin/dev_appserver.sh demos/guestbook/war/
I get the following output, but the server does not start up:
2011-03-13 17:52:43.404 java[839:80f] [Java CocoaComponent compatibility mode]: Enabled

Warning: Future versions of the Dev App Server will require Java 1.6 or later. Please upgrade your JRE.

I see the warning about upgrading the JRE, but I don't think this is the problem, as there are no exceptions reported. It just won't start up. I've tried creating a hello world app from within Eclipse using the plugin and running as Web server, but that also spits out the same text but does not start up the web server.
Any idea what I'm doing wrong and how to remedy the problem?
By changing the line in dev_appserver.sh to
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Commands/java -ea -cp "$JAR_FILE" \
com.google.appengine.tools.KickStart \
com.google.appengine.tools.development.DevAppServerMain $*
instead of using the default java (which is set to 1.5.0_26 as I mentioned earlier) the web server starts up.
I had the same problem and simply tried running Eclipse as Administrator and then debugging worked fine.
