Recently, a second beta of Java 6 was
[released](http://java.sun.com/javase/downloads/ea.jsp), which triggered
a
[patch](http://lists.alioth.debian.org/pipermail/pkg-java-maintainers/2006-June/008385.html)
for the [Debian](http://www.debian.org/)
[java-package](http://packages.debian.org/java-package) package. It was
a Bioclipse [bug
report](http://sourceforge.net/tracker/index.php?func=detail&aid=1532612&group_id=150681&atid=778609)
today, however, which made me patch my java-package setup and install
the beta.

So, next thing was to try to get the [CDK](http://cdk.sf.net/) compile
with the Java 6 beta. Because our build system uses JavaDoc (anyone with
a pointer with a easy to use Java parser, which parses JavaDoc too?),
and because this setup is different for literally every platform and
Java version, the
[build.xml](http://svn.sourceforge.net/viewvc/cdk/trunk/cdk/build.xml?view=log)
needed some tweaking (patch 6719 and 6721). Additionally, a number of
source files were marked as needing Java 1.5, while they actually depend
on features introduced in Java 5 (aka 1.5) and which are present in Java
6 (aka 1.6) too, so that needed some tweaking too (patch 6720).

I have no idea what Java 6 will change and/or introduce, but I did note
some comments on it being faster, which is always a good thing. The
[JUnit](http://www.junit.org/) test timings seems to agree with this.
While my Java 1.5.0_06 installation needed 204 seconds (no duplicates),
Java 1.6.0_beta2 needed only 168 seconds (no duplicates), and
improvement of 18%.
