Eclipse and Java 1.6
Ever since Sun ‘refreshed’ Java 1.6. with the _04 version, Eclipse became unstable for me. After some googleing, it seems that this is actually a known problem with some changes in the JIT compiler that surfaced in _04 and beyond.
Adding
-XX:CompileCommand=exclude,org/eclipse/core/internal/dtree/DataTreeNode,forwardDeltaWith -XX:CompileCommand=exclude,org/eclipse/jdt/internal/compiler/lookup/ParameterizedMethodBinding,<init>
to the eclipse command (or .eclipserc, depending on your installation) made it stable again. So Sun, could you please fix this bug?

Last week, I went to the first meeting of the Java User Group Erlangen-Nürnberg. Seems that we finally get a JUG here, too. If you are interested, the group meets every month, on the second thursday. Web site is at http://www.jug-ern.de/.
Invitation was a bit late, so only a few people outside the organizing company showed up. The talk was ok, however I wasn’t able to join for dinner afterwards, so I don’t know much about the social part yet. I consider going again in March, though.

Sometimes I go to PGP Key Signing parties, often at some conference that I attend. While the key signing party itself is fun, there is a boring (and error prone) part of key signing that I much too often neglect: The actual signing of the keys.
You end up with a piece of paper saying who was present, which keys should be signed and then… you postpone it to another day. I found a list of keys to sign from an event eight months gone. Which sucks.
So in the true spirit of Steven Pembertons keynote at ApacheCon EU 2007 (”let the computer do the work”), I searched an application for this. There are some shell scripts out there that seem to do the job for some people but most of the times, if you ask “how do you sign your keys”, the answer is either “manually” or “I have a self rolled script” (I omitted the third possible answer “I never get around to do it”).
I am a Java Weenie. I hacked a small Java application that lets me do all the steps of reviewing a party key file, signing the keys and mailing them out (also uploading to key servers) from an interactive command line. With command completion, help and all the stuff that one expects in the 21st century.
I met the various usual Java perils (e.g. One-Jar chokes on signed jars, which are needed for JCE or strong crypto under Java needs the Unlimited Strength Policy files installed) but in the end, here is PGPSigner which allowed me to sign the party key lists from the last eight months in about ten minutes (And it was fun to test some stuff I always wanted to check out like PGP key handling in Java).

I finally found the time to put an (internal) branch off the JSP Wiki
tree back to open source. You can get some information about eyeWiki
from
and the tree itself from subversion at
http://svn.softwareforge.de/svn/opensource/eyewiki/trunk/
This is a sort of “technology preview”, I’m not sure if this code is
really ready for production use outside a controlled environment
(i.e. knowing what you are doing. 
. However, I did some pretty deep
changes to the structure of the JSPWiki code (adding Pico, reworking
the variable evaluation process, reworking CSS skinning to name just a
few) and I’d be happy if some of this code might find its way back
into the JSPWiki main tree over time.
