Crash in patchedCompanionSymbolOf in Scala IDE.

[adampauls]

I am seeing a lot exception from the presentation compiler in the Scala IDE that look like the one below. It happens across many classes, and as you can see, it often fails to complete standard library classes. I can't tell if this is a problem in the paradise plugin or in the presentation compiler (or simply the interaction between the two). It sounds like the Scala IDE aren't planning on supporting paradise (https://groups.google.com/forum/#!topic/scala-ide-user/zpfTOh3CUqA), so I thought I'd file an issue here. Hopefully this is a simple fix!
