RFR (XS) 8221400: [TESTBUG] java/lang/String/StringRepeat.java requests too much heap

[Aleksey Shipilev]

Bug:
 https://bugs.openjdk.java.net/browse/JDK-8221400

My major concern is to make tier1 passing on x86_32. This is one of the tests 
that fail. It seems
the test can just use smaller heap size.

Fix:
