RFR: 8279669: test/jdk/com/sun/jdi/TestScaffold.java uses wrong condition

[Zdeněk Žamberský]

Hi,
please review this backport:

JDK Bug: https://bugs.openjdk.java.net/browse/JDK-8279669
Webrev (monojdk8u-dev): 
https://zzambers.github.io/www/webrevs/8279669/webrev.00/

This fixes: test/com/sun/jdi/RedefineCrossEvent.java test.

I manually ran all tests in test/com/sun/jdi and they passed for me with 
this patch applied.
I'll probably also require someone to push on my behalf.
