Error on the first :JavaImportSort

[Steven K. Wong]

Using eclim from source 77b4eb8a4fdd7a6dd19c2b750c0d743a7615bda9 (Thu
Sep 3 21:21:57 2009 -0700): Start Eclipse, start Vim, then immediately
execute the command :JavaImportSort. The command gives the following
error. But if I execute the command again (without restarting Eclipse
or Vim), the error doesn't happen and the command runs fine.

java.lang.NullPointerException

So far I can't reproduce the NPE that you received. I've tried
running the command as quick as I can after eclimd binds to the port,
but the best can do is generate a RuntimeException if I run the
command before it's registered internally in eclimd.

I can fix the vim side to handle the error more gracefully, but I'd
like to find out why you are getting an NPE. Can you try running that
java_import_order command at a command line to retrieve the full stack
trace:

$ $ECLIPSE_HOME/eclim -command java_import_order -p "nccp"

By "immediately" I simply meant I didn't do anything else (execute
other commands, etc.) between starting Vim and
executing :JavaImportSort (other than :e the file). Sorry, didn't mean
to rush you. :)

Here's the stack trace you want:

I just remembered that you're running eclimd inside of the eclipse
gui. Using that mode I can reproduce the issue. I'll work on a fix
for this later today.

This was pretty quick to fix, so I went ahead and did it. Pull the
latest code and that should resolve the error.

Yes, it's fixed.
