> 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/ folder.
> 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.
