Bug 14421 Old .CLASS Files Are Not Deleted
When creating a project that does NOT use source folders (and does not use a bin directory for .class files) the .java and .class files are stored together in the Java package structure. When converting a project to use source folders (and the required bin directory for .class files), the old .class files stored in the Java package structure are NEVER DELETED by Eclipse. This is a bug for Eclipse 1.0 and 2.0. Since I use WSDD 4.0 (which is built on Eclipse 1.0), I've seen compilation errors due to the fact that the compiler/JDT is using old .class files rather than the new ones in the project's bin directory. I have not managed to reproduce the compile errors in build 20020416. But since the old .class files should have been deleted this is still a bug for the latest build.
