RuntimeException when trying to load file with unknown extension

[WrongWayGC]

The following exception is thrown in my installation since several revisions when starting josm. Beside the exception dialog being shown nothing bad seems to happen.

Trace in terminal: java.lang.RuntimeException

This happens if you start josm from the command line and add a file that has an unknown extension:
E.g. java -jar josm-latest.jar test.exe

How do you start josm? Do you use a script?

In any case, just throwing an exception without any explanation is certainly not the right thing to do.

Okay, I could trace this down to me using the following script, where the jar is given first:

#!/bin/sh java -jar josm-latest.jar -Xmx512m -Dsun.java2d.opengl=true

When I put the -jar option last, the problem is gone. This is clearly my fault as java -h says that the -jar option has to go last (for whatever reason?). The proper way is:

#!/bin/sh java -Xmx512m -Dsun.java2d.opengl=true -jar josm-latest.jar

Excuse me for bringing up this bogous bug report and thank you very much for quickly helping and pointing me towards the proper solution.
