Description

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.

(Incidentally: after fixing that I also hit an NPE from Ant on a later stage of the javadoc build. That was fixed by moving from ant 1.9.3 to ant 1.9.4):
