If Xalan is on the classpath, it gets picked up, otherwise on java1.5+ 
the default XSL engine is the variant of xalan that comes in the JVM, 
and it is very memory hungry.

If you run ant -diagnostics you will see which engine you get; if it is 
the one in the JVM, stick a xalan-2.7.x into your ANT_HOME/lib

PermGen heapspace is a separate problem. On the BEA/Oracle JRockit JVM, 
it never occurs, they just have one big heap, instead of a separate heap 
for class information. But you can't download that for free any more.

Try the 64 bit jvm with compressed pointers; its got a big heap with 
small pointers, not as good as JRockit, but a good second best.
