RFR(S) : 8019915 : whitebox testClearMethodStateTest fails with tiered on sparc

[Vladimir Kozlov]

Igor,

Two things.
First, could you explain what do you mean under "queue overloaded"?

Could you fix all white box test to not print by default 
System.out.println("method was invoked " + count + " times");?

The same for these chagnes:
System.out.printf("Compiler queue size is %d, waiting...%n", size);

Can you put this under debugging flag (-Dverbose) so when we do normal 
jtreg runs they will not print it? They really pollute jtreg output, see 
the output file IsMethodCompilableTest.jtr from the bug report.

I think you can partially avoid the problem if you use CICompilerCount=1.

Is it possible that a method is compiled before your (401) count because 
of Tiered compilation? C1 in Tiered has threshold = 100.

thanks,
Vladimir
