[josm-dev] Latest josm seems to be crashing Xorg

[ael]

I am not sure what is happeing here, but downloading the latest
josm version a few minutes ago and attempting to run it crashes 
Xorg with "Bus error at address 0x0".

I am on debian testing, and using

java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)

Running my usual "java -jar ~/mapping/josm-latest.jar &"
crashes X.

Here is the extract from Xorg.0.log:

I might try to open a ticket, but the last time I tried that, it seemed
to vanish :-(
