RFR(S): 8191229: serviceability/jvmti/GetOwnedMonitorInfo/GetOwnedMonitorInfoTest.java fails with NoClassDefFoundError

[Yasumasa Suenaga]

Hi Chris,

I added testcase of GetOwnedMonitorInfo in JDK-8185164.
I have concern your change to cache the result of FindClass().

According to [1], FindClass() calls find_class_from_class_loader(), it returns JNI local value.
Is it safe to cache?

So I called FindClass each time in original commit.


Thanks,

Yasumasa
