following error occured during compiling my project. here is exception from log. see java file below (i removed all methods except one, so there are a lot of comiplation errors, but the problem occurs even if all is okay there) !ENTRY org.eclipse.core.resources 2 75 Jul 25, 2003 15:12:34.100 !MESSAGE Errors during build. !SUBENTRY 1 org.eclipse.jdt.core 2 75 Jul 25, 2003 15:12:34.100 !MESSAGE org.eclipse.jdt.internal.compiler.lookup.ArrayBinding !STACK 0 java.lang.ClassCastException: org.eclipse.jdt.internal.compiler.lookup.ArrayBinding at org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveType (MessageSend.java:273) at org.eclipse.jdt.internal.compiler.ast.Expression.resolveTypeExpecting (Expression.java:447) at org.eclipse.jdt.internal.compiler.ast.IfStatement.resolve (IfStatement.java:258) at org.eclipse.jdt.internal.compiler.ast.Block.resolve(Block.java:108) at org.eclipse.jdt.internal.compiler.ast.ForStatement.resolve (ForStatement.java:321) at org.eclipse.jdt.internal.compiler.ast.Block.resolve(Block.java:108) at org.eclipse.jdt.internal.compiler.ast.IfStatement.resolve (IfStatement.java:261) at org.eclipse.jdt.internal.compiler.ast.Block.resolve(Block.java:108) at org.eclipse.jdt.internal.compiler.ast.IfStatement.resolve (IfStatement.java:261) at org.eclipse.jdt.internal.compiler.ast.Block.resolve(Block.java:108) at org.eclipse.jdt.internal.compiler.ast.IfStatement.resolve (IfStatement.java:261) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolveStatement s(AbstractMethodDeclaration.java:361) at org.eclipse.jdt.internal.compiler.ast.MethodDeclaration.resolveStatements (MethodDeclaration.java:140) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolve (AbstractMethodDeclaration.java:351) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve (TypeDeclaration.java:846) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve (TypeDeclaration.java:887) at org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration.resolve (CompilationUnitDeclaration.java:270) at org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:533) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:328) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile (AbstractImageBuilder.java:198) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile (AbstractImageBuilder.java:171) at org.eclipse.jdt.internal.core.builder.BatchImageBuilder.build (BatchImageBuilder.java:51) package com.bc.pt.graphing; import java.awt.*; import java.io.*; import java.util.*; import com.bc.expr.*; /** * This class is for drawing one graph */ public class SimpleGraph { /** * Get orientation of graph.

i put my current oth.eclipse.jdt.core (patched) to 3.0 M2 and it solved the problem.
Reproduced on simple test case: public class X { public void foo(Map map) { int[] fillPattern = new int[0]; if (fillPattern.equals((int[])map.get("x"))) { } } }
Contributed fix is good. Integrated. Regression test added.
Fixed
Thanks for the patch, makes our life much easier <g>
