When building a Maven 2 project with goal site the first time the project is
build correctly. However the second time the build returns an OutOfMemoryError
when archiving the results of the first subproject. Removing previous builds and
rebuilding works fine. But as soon as one or more previous builds are maintained
the error occurs.

Heap space is set to 1,5 GB. The build machine has 6 GB of virtual memory.
