The error re-appears if I try to zoom.
Invoked JOSM with command

/usr/local/java/jdk1.6.0_02/bin/java -Dsun.java2d.opengl=True -jar josm-latest.jar

in a rather standard Etch installation.

Repeatable. Occurs also without the -D switch. Another error message:

Update to ticket by submitter:

The problem disappears after correcting "JAVA_HOME" variable, an inconsistency which appeared during previous java upgrade.

The problem did not appear with the JOSM that used old API, hence it took some time to find out that it was eventually stupid user problem..

If you want to make the tool perfect, then would it be possible to detect such a situation?
If not, then feel free to close this ticket.

This is caused by an old mappaint version. You need a new one since 0.5 -- just update it.
