> Key: PIG-3922
> URL: https://issues.apache.org/jira/browse/PIG-3922
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Philip (flip) Kromer
> Priority: Minor
> Labels: ant, build, docs, fop, forrest, javadoc
> Attachments:
> 0001-Increased-Forrest-heap-size-to-fix-build-of-docs.patch
>
>
> Trying to build the 'tar' target fails for me with an OutOfMemoryError from
> forrest deep in the build process.
> The attached patch increases the heap size for the forrest task from 64m to
> 256m by changing the single line 'forrest.maxmemory=256m' in
> src/docs/forrest.properties.
> Here's the stacktrace, mostly to make the issue more googleable.
