Also the test fails locally on RHEL9.6, even if the JVM_SEARCH_BASE=/usr/lib/jvm/ is specified which points to the root directory that contains all LTS versions of Java from 8 to 25.

@stephan-herrmann : FYI.

@laeubi : could you please check what is wrong & fix the test?

I assume SDK tests run on some instance where not all VM's are available or available but can't be found like on my RHEL 9.6.

I'll try to take a look whats going on, maybe we need to specify a different base path.

Looking at the exception it seems not related to the java versions, it more looks like it is missing the project content.
