[Bug] Unsolved symbol error java.lang.String with javasrc frontend
Describe the bug I have a VM where this can be replicated for all java projects with joern-parse and importCode on the shell.
Below is a stack trace.

To Reproduce Steps to reproduce the behavior: Only happens on certain VMs so far. I can reproduce this on a powerpc VM. This bug is not due to the CPU architecture but the symbol solver relying on specific jdk jars for primitive types.
Expected behavior jdk symbol solver should work primitive types without relying on jdk jars.
Screenshots If applicable, add screenshots to help explain your problem.
Desktop (please complete the following information):
- OS - powerpc so far.
