RFR:(S): 8164562: serviceability/sa/TestInstanceKlassSizeForInterface.java: fails with NPE

[Jini Susan George]

Thank you, Mandy. The test was throwing an NPE due to the option “-XX:+UnlockDiagnosticVMOptions” not being used for TestInstanceKlassSizeForInterface.java in the release build. jcmd’s GC.class_stats requires this, and hence, parsing of the jcmd output was resulting in an NPE. 

 

Regards,

Jini.

Hi all, 

 

Could you please review the fix for: 

 

Bug: https://bugs.openjdk.java.net/browse/JDK-8164562

Webrev: http://cr.openjdk.java.net/~jgeorge/8164562/webrev.00/

 

I took the liberty to do some module related cleanups in the test also while fixing this issue. 

 

 

The @module cleanup looks fine to workaround https://bugs.openjdk.java.net/browse/CODETOOLS-7901761

 

What causes the test to throw NPE?  It's unclear to me.
