Run Jbuilder in verbose mode (-verbose on the command-line). Then...
well on Windows you do a Ctrl-Break to get a thread-dump when a java
application hangs. I'm sure there is something similar for Linux.

Follow-ups set to the .linux group, since that is where the knowledgable
Linux people hang out.

That pretty much tells you the problem. It is choking on a non-UTF8
character in your file.

Interesting. Is your project set up with a non-UTF8 character set?

[Dr. Michael Boeni]

erm...I have no idea. I did not change any default setting or so. i just
copied the file tree from Windows XP, perhaps that mangled a file.

I work on a "Swissgerman" system, that might also be a problem. How to
resolve this now?

BTW, I get this with ALL files that I copy from Windows. What to do here?

Sounds as though you are using a Windows EOL marker, which will give you a
character (like ^M) in your file, as an EOL marker.

To see if this is the case, open the file on the Unix machine using VI or
EMACS. If you see non standard characters in the file (BOL, EOL), then you
have correctly identified the culprit.

This is a common thing when using something like WordPad that does not, by
default using ANSI text.
