> After updating to nb-javac 1.51, when I try to open a class in a binary .jar
> file, it often fails with an exception like this
> java.lang.ClassCastException: com.sun.tools.javac.code.Type$ClassType cannot
> be cast to com.sun.tools.javac.code.Type$ErrorType
> at
> org.netbeans.modules.java.source.builder.TreeFactory.Type(TreeFactory.java:797)
> at org.netbeans.api.java.source.TreeMaker.Type(TreeMaker.java:1083)
> at
> org.netbeans.modules.java.classfile.CodeGenerator$TreeBuilder.visitExecutable(CodeGenerator.java:549)

> This happens whenever the class references a class in a different .jar. For

> of the various classes referenced from the httpcore dependency.
> It looks like this started once

> was merged into nb-javac - TreeFactory's assumption that getKind()==ERROR
> implies ErrorType is no longer true.
