Use '-Xcheck:jni' during testsuite run to detect JNI bugs (#218)

Motivation:

We should run our testsuite with '-Xcheck:jni' to ensure we catch bugs
in our JNI code which could later cause issues like crashes

Modifications:

- Add -Xcheck:jni

Result:

Testsuite will be able to catch more JNI bugs
