[jdk17] RFR: 8271160: runtime/jni/checked/TestCheckedJniExceptionCheck.java doesn't set -Djava.library.path

[Igor Ignatyev]

Hi all,

could you please review this small patch that sets `-Djava.library.path` to ` test.nativepath` for `TestCheckedJniExceptionCheck`'s child JVM so it will be able to locate the library?

from JBS:
> TestCheckedJniExceptionCheck spawns a child JVM that uses a test native library, TestCheckedJniExceptionCheck, but it doesn't add/set test.nativepath value to -Djava.library.path, so the child JVM can't find the library and fails. 
>
> this issue hasn't been noticed early b/c TestCheckedJniExceptionCheck doesn't check the exit code of the child JVM.

Thanks,
-- Igor
