Fixed on Java raw types and Scala existential type and conversions between them.
Don't use skolemized type for functions parameters, use existential type instead.
#SCL-5089 Fixed.
EA-42092.
Typed pattern inference on Java classes with bounded type parameters.
Changed error messages for SCL-5021.
Better support of Java varargs. It's possible to override in Scala by Scala repeated parameters.
Fixed read access exception in Find Usages.
More red code fixes
Don't check doc comment links for accessibility.
Typo fixed
AllIcons used in compile server managers
Compile server: substitute stdout
Ant build: add nailgun.jar to Runners classpath
Last "good code is red"  example in .scala files of scala plugin production code is fixed now.
If expected type for pattern is existential type, don't forget to skolemize it.
No 'scala-library*.jar' warning
Transfer compile server exceptions as strings
Quick fix for ScalaLanguageLevel crashing with External build compiler

ScalaLanguageLevel.getLanguageLevel(element) would crash if
element.getContainingFile.getVirtualFile was null. This would pretty
much kill any Completion/Highlighting processes that touched it, as
in this bug report against Completion:

http://youtrack.jetbrains.com/issue/SCL-5108

I think getVirtualFile() is supposed to return null iff the file
exists only in memory, however this was occurring for me with Scala
0.7.62/IU-123.94 on concrete *.scala source files.

I previously thought that this was occurring only when 'Use External
build' was enabled, but in fact the problem with getVirtualFile()
returning null seems independent of that.
