David Grove reassigned RVM-701:

> ----------------------------------------------------------
>
> Key: RVM-701
> URL: http://jira.codehaus.org/browse/RVM-701
> Project: RVM
> Issue Type: Bug
> Affects Versions: 3.0.1
> Environment: Ubuntu 8.10, ia-32 and some Debian machine
> Reporter: Jan Sinschek
> Assignee: David Grove
> Fix For: 3.1.0
>
> Attachments: .ant.properties, trivialType.class

> The VM crashes when trying to output its edge counters or dynamic call graph: using -X:aos:final_report_level=2 with a build that includes the AOS or -X:base:edge_counter=true when there is none, an error will occur after the target program has terminated and the values should be shown. I show the output below. The problem might be related to that described here [http://article.gmane.org/gmane.comp.java.jikes.rvm.devel/5919], though the proposed fix does not work. It might also be related to this issue: [http://www.nabble.com/Re%3A--rvm-research--ThreadLocalMap.get()-throws-NPE-during-shutdown-exit-to17351797.html#a17351797].
