Multiple bugs/crashes on DaCapo while varying JIT configurations

                 Key: HARMONY-6026
                 URL: https://issues.apache.org/jira/browse/HARMONY-6026
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
    Affects Versions: 5.0M7
         Environment: Gentoo x86, Harmony M7, DaCapo MR2 
            Reporter: Aleksey Shipilev
         Attachments: test-emconfs.tar.gz

This is the contribution of test cases which were failed while varying RVM command line parameters.
Parameters were swizzled by custom-made GA framework developed for getting my MSc degree.
Though this result is not the primary, it really makes the fuzzy testing of RVM and effectively
produces the reliability test.

To use the materials, one should download test-emconfs.tar.gz, unpack it and explore the test-emconfs/

The failures were classified by benchmark and the type of crash occured. Each report file
names as ${benchmark}${type_of_crash}${N}.report, where ${benchmark} is the DaCapo test on
which the failure was observed, and ${type_of_crash} is the type of failure occured, as follows:
a. (3195 cases) "GPF", General protection fault signal caught
b. (1237 cases) "SpillGen", "Jitrino crashed // SpillGen failed" received
c. (496 cases) "IMSE", java.lang.IllegalMonitorStateException caught
d. (270 cases) "JIT-LIR", "JIT helper is not supported in LIR" was received
e. (260 cases) "ABORT", Abort signal caught
f. (124 cases) "unknown", not-classified failures, hangups, timeouts, etc.
g. (95 cases) "NPE", java.lang.NullPointerException caught
h. (39 cases) "Dacapo-failed", DaCapo has failed the verification

There are totally 5716 test cases. Not all of them were verified to reproduce, it's just the
excerpt from search log.
