------------------------------------------
In the hopes of helping with the debugging effort, we went and took a bunch of
thread dumps over and over again while it was building up its memory usage. It
appears to just sit in the same code and accumulate memory. Here's a trace of
where:

> REOPEN - OutOfMemory when running maven-assembly-plugin
> -------------------------------------------------------
>
> Key: MASSEMBLY-651
> URL: https://jira.codehaus.org/browse/MASSEMBLY-651
> Project: Maven 2.x Assembly Plugin
> Issue Type: Bug
> Affects Versions: 2.4
> Environment: Ubuntu 12.04, Oracle JDK 6
> Reporter: Eric Tschetter
> Attachments: log.txt
>
>
> I'm experiencing OutOfMemory error when maven build try to complete
> maven-assembly-plugin job.
> Issue reproducible on Linux only.
> The project I'm trying to build is
> [webcam-capture|https://github.com/sarxos/webcam-capture].
> Command:
> {code}
> $ mvn clean package -P assembly -X
> {code}
> It hangs always in the same place:
> {code}
> [DEBUG] Adding file-set in:
> /home/sarxos/workspace-j2se/webcam-capture/webcam-capture/./src/example/java
> to archive location: examples/
> {code}
> In most cases process hangs and I'm getting OutOfMemory. Once I get this
> exception in the same time, before process started to allocate huge amount of
> memory OutOfMemory. OldGen is exhausted. Increasing memory to be allocated
> does not have any effect.
> Not sure if exception below is cause or effect.
