RFR: 8335778: runtime/ClassInitErrors/TestStackOverflowDuringInit.java fails on ppc64 platforms after JDK-8334545

[Matthias Baesken]

stdout shows :
 "The Java thread stack size specified is too small. Specify at least 384k"
Previously the test was done only on x64 platforms (comment said that it only works there 'in desired way') .
