StackWalkerTest testGetCallerClass caller class wrong about openj9

[pshipton]

There are many failures in sanity.openjdk which are likely caused by the same change.
I ran the first set of failures with the change reverted and they passed.

SC_Softmx_JitAot also passed with the change reverted so this extended.system test failure appears to also have the same cause.
SC_Softmx_JitAot_0
SC_Softmx_JitAot_1
SC_Softmx_JitAot_Linux_0
SC_Softmx_JitAot_Linux_1

In jdk17+, StackWalkerTest hangs.

Also spotted these related failures, some of there where the GEN process times out. This could affect other system tests.

Not sure if this is related, probably.

Looks like the failure occurred in StackWalkerTest_1 -Xjit:count=0 is a conflicting use of vmThread->stackWalkState updated in #18926, I will rework the solution to avoid this issue.

[pshipton]

Since the change was reverted I'll close this.
