jstype.UnionType cannot be cast to jstype.ObjectType #14

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Use plovr with Closure Compiler svn r506 (maybe earlier too?); plovr serve 
something that compiles with ADVANCED_OPTIMIZATIONS.
2. Hit the /compile?id=something URL
3. Look in the terminal for this error:

I don't really know whether plovr is using its own Closure Compiler jar, or my 
parallel checkout.  But with a parallel checkout of Closure Compiler svn r506, 
plovr r75b7109779 works, while r1f627faf52 fails with that traceback above.

works:

And with the latest version of plovr, Compiler r481 works for me while r482 
doesn't.  I'll go report the bug with Compiler.  Feel free to close this; sorry 
for the noise.
