Hybris, ant clean all command failes with message Error occurred during initialization of VM

I'm getting this error while trying to build my Hybris project via ant clean all && ./hybrisserver.sh debug:
Error occurred during initialization of VM
java.lang.Error: Could not create SecurityManager

Maybe I put a typo somewhere (see Caused by: java.lang.ClassNotFoundException: allow
) but I can't find anything and my repo's up to date with master which is correctly working, Is there a way to find the problem?
Note: i have Ubuntu 20.04.5 LTS
Thank you

Solution was simple:
Somehow I lost my setantenv.sh configuration, i had to re-run it in /platform

New to Java here. Using IntelliJ. I wrote a simple "helloworld" Spring application that compiles just fine, but when I run it receive the following error:

I suspect that it may have to do with the CLASSPATH. I tried setting the CLASSPATH environment variable, as well as adding this to the java command
-cp /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home
But that does not seem to work. Might I have the incorrect CLASSPATH?

The comments about the module-info file led me to some clues. I took notice that IntelliJ seems to have created a module-info.java file with the following contents:
module SpringHelloWorld {
requires spring.context;
}
Did not realizing I was compiling a module. I deleted that file along with everything in the bin directory. Then I was able to run it by the Run menu using this option:
I can run it on the command line via:
java -Dfile.encoding=UTF-8 -classpath /Users/.../java-spring-helloworld/bin:/Users/.../<spring-framework-libs>... com.wakproductions.MainApp

Cannot run WOInstaller.jar and thus cannot create frameworks in WOLips

I am installing WOLips. I have installed the plugins in Eclipse and everything seems fine (except Goodies won't install). I have tried to run WOInstaller.jar but I get a "connection time out" error:
$ sudo java -jar WOInstaller.jar 5.4.3 $HOME/workspace/WebObjects543/Versions/WebObjects543.
Exception in thread "main" java.net.ConnectException: Connection timed out at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
This is the build recommended for my version of Eclipse on Debian. Any ideas?

I solved it. It was a proxy problem. Using java -Dhttp.proxyHost=10.0.0.0 -Dhttp.proxyPort=8080 -jar etc. it works!

Nutch 2.1 - generator job runtime exception job failed

I am getting the below error when i try to generate urls using the generate command:
GeneratorJob: java.lang.RuntimeException: job failed: name=generate: 1357474131-234134646, jobid=job_local_0001

The generate, fetch and parse were working fine, but updatedb was giving this error before sometimes:

Now, it is continuously giving generate job failed. What might be the issue? Can it be mysql issue?

The above errors are due to insufficient space on the partition on the server where i have installed . check the answer at Insufficient space for shared memory file when i try to run nutch generate command
