[7u-dev] Request for approval for 8024027 Test sun/misc/IoTrace/IoTraceSocketReadWrite.java crashes VM

[Staffan Larsen]

I would like to push this test fix to 7u-dev. This fix is only applicable to jdk7.

This test uses byte code instrumentation and there were two errors in the test which under some circumstances caused the VM to crash. I have updated the test to run with -Xverify:all which would have caught the problems earlier. The other changes add a missing ALOAD instruction and make sure that ASM does the max stack size calculation for us.
