nsk/regression/b4675027 crashes due to OOM during method compilation.

It crashes when it tries to load com.sun.tools.hat.internal.oql.OQLEngine and all its dependencies.
The problematic method is:
sun.org.mozilla.javascript.internal.Interpreter::interpretLoop(7102 bytes)

Only 32-bit Server VM on Windows in comp mode is affected when G1 is used. I wasn't able to reproduce the crash in other modes.

Simplified test case:
public class Test {
    public static void main(String args[]) throws Exception {
        Class initClass = Class.forName("com.sun.tools.hat.internal.oql.OQLEngine");
    }
}

The test fails from at least b120 to b125 (hs20-b03 to hs20-b06). Starting b126 it stops failing, though VM version is the same (hs20-b06). I suppose some JDK changes hid the bug.

How to reproduce:
   - login to vmsqe-xeon-05.russia
   - java -server -Xcomp -XX:+UseG1GC -cp .;%JDK%/lib/tools.jar Test
   or
   - cd cd K:/execution/results/JDK7/PROMOTION/VM/7/b122/G1/vm/windows-i586/server/comp/windows-i586_vm__server_comp_nsk.regression.testlist/ResultDir/b4675027
   - bash rerun.sh
