I have recently updated from RAD 8.5.1 to RAD 9.0.1.3. I am trying to run as JUnit a project that was executing under 8.5.1, and now I am getting an error:
java.lang.NoClassDefFoundError: org.DataFactory
The dataclass in the project and it opens in the editor with no problem. Cleaning the project did not report any errors. Going thru Maven and updating the project does not resolve the issue, The error presents only at run time.
No other changes have been made other than upgrading the version of RAD.

In Eclipse I have for some reason since last week a weird error while using Groovy. I never seen this error before and a search shows that I seems to be the only one.

I have no clue why I get this. I'm not using Swing or Groovy Swing anywhere. It's not JUnit 5 related because I got this also from Guice.
This should be related with Eclipse because if I compile it in Maven it runs fine. Currently I need to do a mvn clean install so that it runs again in Eclipse.
Eclipse Version: 2022-06 (4.24.0)
Build id: 20220609-1112
Groovy 3.0.14
Run in Eclipse. Groovy is added as dependency. It should run without errors.
I am developing a JEE project using Eclipse JEE (2019-09), Maven, Wildfly 17, JSF, PrimeFaces 7.0 running on Ubuntu 18.04.
My project used to compile, deploy and run on the WildFly 17 server until today. However, because I recieved strange errors when debugging, I installed an earlier Eclipse IDE to try to run my project on it.
After installing the older version of Eclipse (2019-03) in its own dedicated workspace, I got this error message when deploying my application to WildFly:
Caused by: java.lang.RuntimeException: WFLYSRV0177: Error getting reflective information for class
I then switched back to my initial Eclipse JEE (2019-09) Version, but then I kept recieving the same error message upon deploying.
I' ve searched the internet and found these two similar problems:
Error getting reflective information for class
Wildfly: Error getting reflective information for class
but actually not a solution to my problem.
Could somebody please help?
The problem was that the Maven jar- dependencies were not added to the WEB-INF/lib path.
Actually, in the deployed .war file the folder WEB-INF/lib was completely missing.
I fixed the problem by right-mouse click on my project in Eclipse, then "Properties", then "Deployment Assembly".
I added the missing entry "Maven Dependencies" as follows:
1.) BEFORE MY FIX:
2.) AFTER MY FIX:
When I run a JUnit 4 test using Code Coverage from within the Eclipse IDE, All I get is a dialog saying "An internal error occurred during: "Launching AlgebraicNumberTest".
java.lang.NullPointerException"
The same JUnit test runs fine under the debugger or using just plain run or from a gradle command line. Code coverage works fine when running the main application rather than JUnit tests. I just can't get Code Coverage and the JUnit test to work together. They were working together on this project at one point several months ago. I don't know what's changed.
I'm using JUnit 4.12 and Eclipse Oxygen.3a Release (4.7.3a).

I found the Eclipse log file at %USERPROFILE%\eclipse-workspace.metadata.log.
Here's the exception detail from the log file:

I uninstalled the "VisualVM Launcher Feature 1.1.2" plugin as suggested by #Godin. That seems to have resolved the problem that I originally posted.
I plan to eventually reinstall VisualVM. If it causes any problems, I'll post a new question.
Thanks all.
I'm using Eclipse Neon from the release date. Yesterday I got some strange errors in Eclipse and after a reboot of the Eclipse instance everything was gone. I installed Eclipse and my plugins again. Everything is working again but when I launch the Java debugger on one of my project I got the error:
An internal error occurred during: "XXXX".
java.lang.NullPointerException
This error occurs on debugging all my projects also in another workspace. Can someone help me with this? The error is not explaining what the exact problem is.
In the logfile of Eclipse I can found the follow error:

Are you using Eclipse Luna for Java Developers (as opposed to Eclipse Classic) AND Scala IDE 4.0 milestone 3? There is a known issue (solved in the nightly builds since then), reported on the mailing list here.
You can "fix" it by either upgrading the Scala plugin to a nightly build (they're pretty stable), or going with Eclipse Classic instead.
