Okay, I think I've tracked this...

In Java release up to (and including) 1.3, StringBuffers just
had an append(Object) method.  This worked for all sorts of things,
including appending the contents of one StringBuffer to another.

JDK1.4 has a special method, append(StringBuffer) for this case.

The upshot of this is that code which does this will compile
and run on all JDKs, but binaries compiled on 1.4 won't run
on earlier JDKs.  Ugh...

Anyway, I'll remember to switch back to JDK1.3 for compiling
binary releases.  I'll try to get a new snapshot out soon.  In
the mean time, a version compiled from the corresponding source
release will work fine...
