After a long investigation, I thought the jar package icu4j=5F3.4.4 was=20
not loaded by DRLVM. And I modified
build\make\targets\kernel.test.xml:
Line 204: <jvmarg=20
value=3D"-Xbootclasspath/p:c:\spark\drlvm\build\deploy\jre\lib\boot\icu4j=
=5F3.4.4\icu4j=5F3=5F4=5F4.jar"=20
/>
then no more NPE will be thrown out.

I want to reproduce this bug on r449972, but as another thread [[drlvm]=20
none of kernel tests passed for the recent sources] depicts.
So I could not verify whether this is a work around. Could anyone gives=20
a hint?

Best regards
