Do you think this is a drlvm issue or a classlib issue?
I guess it is an integration issue, i.e., ICU4J's UCharacter needs to
load some resources for initialization, while at that time on DRLVM,
some necessary kernel classes haven't been inited, so that the
UCharacter cannot load these properties sucessfully and leave them to
null. I'll roll back the patch for Character temporarily if no one
objects, and will look inside later(I need to checkout ICU4J's source
at first ...).
Fascinating. What are we missing in DRLVM?
After a long investigation, I thought the jar package icu4j_3.4.4 was
not loaded by DRLVM. And I modified
build\make\targets\kernel.test.xml:
Line 204: <jvmarg
value="-Xbootclasspath/p:c:\spark\drlvm\build\deploy\jre\lib\boot\icu4j_3.4.4\icu4j_3_4_4.jar"
/>
then no more NPE will be thrown out.
I want to reproduce this bug on r449972, but as another thread [[drlvm]
none of kernel tests passed for the recent sources] depicts.
So I could not verify whether this is a work around. Could anyone gives
a hint?
Best regards

Does anybody observe this issue? As for Linux all works fine.
Thanks,
