I build my project and received this message: org.eclipse.jdt.internal.compiler.lookup.MemberTypeBinding
Oh I suppose the .log file might help you out: <?xml version="1.0" encoding="UTF-8"?> <log> <log-entry date="Thu May 16 11:04:28 PDT 2002"> <status plugin-id="org.eclipse.core.resources"

Finally was able to get a reproduceable case: A.java: package p2; public class A extends Z { M[] m; } B.java: package p2; public class B { A a; // Z z; void foo() {System.out.println(a.m);} } Z.java: package p2; public class Z { static class M {} } Then with the lot size set to 1 and auto-build off, uncomment the line in B + touch Z.

Hi- I've noticed that this bug seems to have re-appeared in eclipse 3.1RC2- but it disappeared when I rolled back to using 3.1RC1. Here's my .log I hope this is helpful. Please email me if you need more detail- Regards Kevin !SESSION 2005-06-12 16:11:37.494 ----------------------------------------------- eclipse.buildId=I20050610-1757 java.version=1.4.2 java.vendor=Sun Microsystems Inc.
