1. Start empty Eclipse 2. Create Java project 3. In the packages view add a normal folder 4. Add x.txt ==> visible, folder icon switches from package to folder 5. Add testInput.class ==> folder switches back to package and .class file not visible Exception is written to console (see below) Maybe the UI should not allow to add .class files if they can't be handled later. Note that with the default setup (proj = src = bin) it will not be possible to have normal folders (i.e. which aren't on the classpath). This means it is not possible to write a program that uses .java or .class only as input.

org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:98) NOTES: GDA (6/5/01 11:09:21 AM) Recommend to fix. JW (6/5/01 5:35:00 PM) OK to investigate. EG (6/6/2001 3:50:52 AM) Step 5 was done by using the basic New File wizard. This wizard is part of the workbench and doesn't know about Java. The wizard has to be available in the Java UI otherwise users can't create non Java resources like .txt files. This means the UI can't protect the user from this case. The .class file created in step 5 is likely incomplete and the JCORE should check for this. Moving to JCORE, suggest fix if easy. JBL (9/7/2001 12:30:32 PM) No exceptions are logged to the console in 135. JBL (9/7/2001 1:08:54 PM) Was not able to reproduce with the above steps in 118. JBL (9/7/2001 3:53:52 PM) Sent e-mail to DM. DM (9/7/01 7:06:47 PM) In order to see the error you must start Eclipse with -consoleLog or start Eclipse with a batch file to have a console which shows the error. Unfortunately the error is not written to the log. JBL (9/10/2001 3:01:10 PM) Exception is caught and hidden by UI. ClassFile.isClass() throws a JavaModelException if the .class file is not well formed (as specified in IClassFile). Problem is more that ClassFile.exists() returns false. In this case, it should be considered as a non-java resource.
PRODUCT VERSION: 0.118
If project==src, then this is it, no classfile can be treated as input in this project. And the file should be ignored (not even a non-java resource, since all generated classfiles will be in the same boat).
When proj=src=bin, .class files addition/deletion are not reported by the delta processor any longer (see bug 3344). As a result, we don't try to find out if the hierarchy is affected. The .class file will not appear in the package view either. *** This bug has been marked as a duplicate of 3344 ***
