ARM test results

[Xerxes Rånby]

JTREG Errors usually indicate a timeout while running the test.

Gervill are known to generate an "emergency soundbank" at startup, this do take time and hurts user experience.
We should consider pre-generate the "emergency soundbank" it at compile time.

These Find*Bugs tests are known to take hours to run on ARM.

Ed Nevill who designed the ARM assembler interpreter and thumb2 jit found that most of these errors can be circumvented by passing -timeout:3 when running the jtreg zero architectures.
Also passing -Xmx256M -vmoption:-Xmx256M cam help some of the armel jtreg testsuite runs.

You can also argue that all these timed-out tests indicate opportunities to optimize the JVM/class librarys for speed, and they will pass on time when the code are cleaned up.
