RFR - JDK-8134432: [TESTBUG] Rewrite test/runtime/6888954/vmerrors.sh in Java

[George Triantafillou]

Please review this fix for JDK-8134432:

JBS: https://bugs.openjdk.java.net/browse/JDK-8134432
webrev: http://cr.openjdk.java.net/~gtriantafill/8134432/webrev.00/ 
<http://cr.openjdk.java.net/%7Egtriantafill/8134432/webrev.00/>

The test was rewritten in Java, and two previously missing test cases 
were added to the test.

The fix was tested with RBT on all platforms with the JPRT hotspot_all 
testset.  Thanks.
