IllegalArgumentException in java editor code completion
Migrated from http://lampsvn.epfl.ch/trac/scala/ticket/2888
Reporter shaberman
In the default package, make a trait FooTrait, then in a FooJava Java file also in the root package, try FooT<ctrl-splace>, kills the auto completion.
Note that auto completion in Scala files works fine and does not fail.
Also if FooTrait/FooJava are in a package "a", then it works fine as well.

Here is the stack trace from the log. Also, specifically in the FooJava file, I was trying to make a "public FooTrait foo" field.
