Re: flymake integration for the eclipse java compiler

well, maybe i spoke a little too soon.  it works fine for a given
buffer, once i can get it open (using the server-init).  however, each
time i open a new buffer it hangs for a while, then tells me that
beanshell is not responding.  after i reload things once or twice,
restart flymake/bsh, then it's happy for that buffer.  open a new
buffer, same song and dance.  any ideas why it could be hanging like
that?
thanks for your help so far,
