Package: openjdk-6-jdk
Version: 6b24-1.11.1-3
Severity: normal

Dear Maintainer,

jar -x hangs when trying to unjar the jar archive dstm.jar contained in [1]

[1] http://proglang.informatik.uni-freiburg.de/projects/dstm/dstm-0.0.1.zip

Steps to reproduce:

1) wget http://proglang.informatik.uni-freiburg.de/projects/dstm/dstm-0.0.1.zip
2) unzip dstm-0.0.1.zip
3) jar -x dstm.jar

It seems all the thread are waiting for one of them to finish reading
something.

It seems the hang comes from JVM_Read:
