RFR: 8359268: 3 JNI exception pending defect groups in 2 files

[Michael McMahon]

Hi,

This change is a follow on from https://bugs.openjdk.org/browse/JDK-8348986
In a couple of places, the new native code in that fix can potentially throw
an exception while another exception is pending. This needs to be fixed.

Thanks,
Michael
