Java SVN head NPE in gui.botConsole (x86_64?)

Hi all,

Just a bug report I'd like to file regarding the current SVN head revision generating an NPE when run with ant.

For some strange reason, it works with eclipse.

Here's the full output from ant:

[matthew@Desktop Reprap]$ ant run

BUILD SUCCESSFUL

The first is because I don't have a bot connected. The second is the NPE that prevents the control console from popping up.

No idea what causes it, the stack trace severed all the line numbers.

I'd be glad to help debug if there's any commands that you'd like me to run.

I'd debug myself but it doesn't seem to happen with eclipse? I'm not sure, I checked out the head revision into eclipse and also imported the ant file into eclipse. Both worked, although the ant one complained about a missing .stl, I probably put it in the wrong directory or something.

Anyways, let me know if there's anything I can do to help. It'd be nice to run this without having eclipse open =D.

I'm running Fedora F9, x86_64 with openJDK 1.6.

I'll be checking the forums intermittently over the next couple of days. Exams =/

I am having the same problem
this is my output

Exception in thread "main" java.lang.NullPointerException

I am using Linux mint. Have not tried it in eclipse yet. Cause i would like to find a solution for this, it should work with netbeans 6.5
