Bug#306739: jakarta-log4j: FTBFS: 'enum' is a keyword, and may not be used as an identifier
The only packages that haven't moved to liblog4j1.2-java are:
* libjfreereport-java: Upstream comes bundled with 1.2.3, so the switch
should be painless. Patch at #306754.
* jetty-extra: Upstream comes bundled with 1.2.6, and uses features
specific to 1.2; Log4J support is either not used or already broken.
Naive patch at #306761.
I think we can remove jakarta-log4j as soon as #306754 is fixed.
