Hi,

Please review this very small test fix to
serviceability/sa/TestHeapDumpForLargeArray.java:

Bug: https://bugs.openjdk.java.net/browse/JDK-8220707
Webrev: http://cr.openjdk.java.net/~ngasson/8220707/webrev.0/

If you run this test with jtreg option -vmoption:-Xmx512m (or any value < 8g) then it will fail with:

STATUS:Failed.`main' threw exception: java.io.IOException: LingeredApp terminated with non-zero exit code 1

LingeredAppWithLargeArray needs an -Xmx8g argument but this can be overriden by the -Xmx option passed to jtreg, as the default VM arguments are added after the explicit ones when creating the subprocess. It would work fine if they were added in the other order.

Thanks,
Nick
