The following JT_HS test started failing in the 2012-01-10
RT_Baseline nightly after syncing with Main_Baseline:

    compiler/7116216/StackOverflow.java

This test failed in 15 configs (so far).

Here is a snippet from one of the .jtr files:

Since RT_Baseline started failing when sync'ed with Main_Baseline,
I checked Main_Baseline nightly results. This test started failing
in Main_Baseline on 2011-01-04 with the following VM identifier:

    23.0-b10-internal-201201041834.bvandett.merge-to-main

The test failed in 8/8 configs in Main_Baseline.
The test does not show up on either the "New Failures" list or
the "Known Failures" list for the 2012-01-03 nightly in any
baseline. That means that the test either did not fail in any
baseline's nightly prior to 2012-01-04 or that subsuite (JT_HS)
is not executed on the baseline in which the failure originated.

I checked all baseline back to 2011-12-26 and verified that this
test first fails in Main_Baseline on 2012-01-04.
I just realized that this set of error messages:

java.lang.IllegalAccessException: Class com.sun.javatest.regtest.MainWrapper$MainThread can not access a member of class StackOverflow with modifiers "public static"

JavaTest Message: Verify that the class defining the test is
JavaTest Message: declared public (test invoked via reflection)

is coming from the JavaTest/JTREG harness. This is starting
to look like an environment issue.
