RFR(XS): 8055012 - [TESTBUG] NMTHelper fails to parse NMT output

[Christian Tornqvist]

Hi,

 

This is a small update to NMTHelper.java to make it work with recent changes
in the NMT implementation that changed the output format a bit.

 

I've tested the change locally using
java\lang\instrument\RedefineBigClass.sh and
java\lang\instrument\RetransformBigClass.sh

 

Webrev doesn't seem to like whitespace-only changes so I can't post a
webrev, I'm pasting the diff here instead:

     public static long committedDiff() throws Exception {

         String res = (String) executeDcmd("vmNativeMemory", "detail.diff");

Thanks,
