Autocompleter crashes Paste Java as Ceylon #10

This file:

https://raw.githubusercontent.com/ceylon/ceylon-web-ide-backend/master/src/main/java/com/redhat/ceylon/js/repl/Autocompleter.java

Seems to crash the converter.

I'm pretty sure this is caused by the slowness described in #5:

I tried converting from the command line and it works. There is also some code in the file that seems to fail the conversion. If I remove that, then it seems to work when I paste.

Yeah it works from the CLI, but it uses 1.7GB or memory, so of course it will crash in an IDE.
