Problem starting VASSAL

[jmlima]

I’m presented with the following error when starting VASSAL, after installing the latest Java version, any ideas appreciated, as VASL does not show the map window after this error:

Thus spake jmlima:

I’m presented with the following error when starting VASSAL, after
installing the latest Java version, any ideas appreciated, as VASL does
not show the map window after this error:

This is a bug in VASL:

vassalengine.org/tracker/sho … gi?id=4312

You can work around it by uninstalling Java 7 and installing Java 6,
or you can wait for the next release of VASL, which should have a fix
for it. (The bug itself is already fixed, but the fix has not yet made
it to a VASL release.)
