OpenStreetMap
After installing JOSM and Java, I experienced that JOSM is terribly slow and nearly unusable. I'm running it with jamvm currently, because all other Java virtual machines (including Sun's jre, OpenJDK and gcj) didn't work and just showed a white window. Java really sucks and is just bloated non-sense in my opinion.
Anyhow I'm using Merkaartor now which performs quite good on my computer.

It runs very nicely with Sun's Java here.

It turned out to be a Java bug:
$ java -version
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)
This fixed it (as proposed by http://www.suckless.org/dwm/manpage.html):
$ export AWT_TOOLKIT=MToolkit

Java doesn't like compositing window managers.

Well, at least the proprietary version doesn't ;).
