You're quite right. There should be something here, logging the start of a new 
revision.

I'd be little surprised (but only a little, mind) if the problem was the 
BufferedReader not returning anything or returning too early. It is supposed 
to wait until end-of-file.

I think there are two other possibilities. One is that the 'svn log' command 
isn't actually returning anything. The other is that the command is returning 
something, but that something is never matching the headerRE regular 
expression.

If you do manage to recompile, and put

			log.debug("Line: " + line);

immediately after the for(){ but before the switch(), that would at least tell 
us which of the above is the case. It might be an idea to add another 
log.debug() before the for(), so you can tell that you have managed to 
recompile/reinstall Anthill successfully, and aren't just looking at the old 
version.

BTW, what OS are you running Anthill on? And which JVM and which version of 
Subversion? I can tell you it works OK on Linux (Debian testing) with IBM JVM 
1.4.2 and Subversion 1.2.3.

Good luck.
