I've also heard reports that this package compiles properly when using sun-jdk-1.6.0, but does not compile with ibm-jdk-1.4.2. Anyway, it looks like it's the case of using a generation-1 JDK when in fact a generation2-JDK is needed. Here's my emerge --info, if that would be helpful.

Commenting out java5 patch makes it work on java 1.4
Expanding on what Serkan said: The java5.patch is apparently needed to fix #137970, that is, allow dom4j to compile under generation-2 JDKs. So by allowing dom4j to build on generation-2 JDKs, it prevents it from building on generation-1 JDKs. Maybe the patch should be applied conditionally depending on which JDK we're compiling with?
WONTFIX 1.4 vm's are gone.
