RFR 8176471: [TESTBUG] runtime/modules/IgnoreModulePropertiesTest.java fails with OpenJDK: java.lang.RuntimeException: 'java version ' missing from stdout/stderr

Hi,

Please review these fixes for two tests that incorrectly parse the 
output from 'java -version' commands for the open jdk build.

Open Webrevs:

    http://cr.openjdk.java.net/~hseigel/bug_8176471_hs/webrev/

JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8176471

The fixed tests were tested on open fastdebug and product builds, and on 
a fastdebug closed build.

Thanks, Harold
