Hi,
the included Test.java give a segfault in Velocity. I confirmed this
with my java 1.3.1
on Redhat 7.0 and Redhat 7.1. I used the prebuild velocity-1.1.jar .
he included patch to commons-collections solves this (You have only
include the
commons collection jar. So you need to get and to rebuild it.)
I do not know why this works.
The program expects a null-pointer exception, but it gets a segfault.
Doing it my
way works.
( LD_ASSUME_KERNEL=2.2.5 does not help anything.)
