Internal compiler error is reported while building FindBugs project from cvs, http://findbugs.sourceforge.net/ repository path is /cvsroot/findbugs, module findbugs. FindBugs uses 1.5 JDK features. The error is reported on first class in edu.umd.cs.findbugs package: public abstract class AbstractBugReporter implements BugReporter.

Additional info - i use JDK 1.5 build 1.5.0-beta-b32c for Win32
I see the same backtrace on a different project.

Additional info: It is a problem with return value from org.eclipse.jdt.internal.compiler.lookup.TypeVariableBinding.superInterfaces() - return value for object represents followed source snippet was null: ---- package edu.umd.cs.findbugs.graph; import java.io.Serializable; import java.util.Iterator; import edu.umd.cs.findbugs.graph.GraphVertex; import edu.umd.cs.findbugs.graph.GraphEdge; /** * Graph interface; defines the operations used to access and manipulate * a graph. */ public interface Graph < EdgeType extends GraphEdge<EdgeType, VertexType>, VertexType extends GraphVertex<VertexType> > extends Serializable { ---- Therefore this code doesn't work as expected: (starts at line 433 in ReferenceBinding) // at this time lastPosition is -1 ReferenceBinding[] itsInterfaces = currentType.superInterfaces(); // itsInterfaces is null!!! if (itsInterfaces != NoSuperInterfaces) { // lastPosition is incremented here!!!! if (++lastPosition == interfacesToVisit.length) System.arraycopy(interfacesToVisit, 0, interfacesToVisit = new ReferenceBinding[lastPosition * 2][], 0, lastPosition); interfacesToVisit[lastPosition] = itsInterfaces; } } while (searchHierarchy && (currentType = currentType.superclass()) != null); // here is lastPosition >= 0! for (int i = 0; i <= lastPosition; i++) { ReferenceBinding[] interfaces = interfacesToVisit[i]; // and here is NPE, because "interfaces" is null: for (int j = 0, length = interfaces.length; j < length; j++) {
