From an email following an EC message. I was using R1.0 (Build 0.127) when I was getting this problem. After obtaining the latest build (1127) I did not get the compiler error. But there were two other problems : [...] I hit the Type Viewer button again. This time it seemed to index all the files, but stopped at the last one and failed with an exception saying - please see log. The message in the log is : 1 org.eclipse.core.resources 4 Unhandled exception caught in event loop.

I'm not checking for Type names which are empty. I would assume that any type has a name with a length >= 1. I could make it more robust by checking for empty type names, but that would introduce additional overhead for sorting. I'd like to know how it is possible that a type name happens to be empty and if I should deal with it.
make the code save and log when the problem occurs.
implemented workaround > 20011127 the bug remains open to understand why the type name can be empty.
fixed a bug in the workaround > 20011206.
Olivier, can you figure out why the type name happens to be empty and file an appropriate bug? I can't reproduce this behaviour with my workspace.
*** Bug 6720 has been marked as a duplicate of this bug. ***
Will look into it and identify the component which is failing to produce correct type names.
I am not quite sure that this is the same as 6720, because I was able to workaround the problem (#6720) by using an older version of org.eclipse.jdt.internal.ui.dialogs.FilteredList.LabelComparator (two weeks old). #6720 seemed to be a problem introduced by case-sensitivity of the dialog (?) ...
Trust me. It is the same bug.
Sorry I cannot help. I didn't get the case myself. I simply entered a PR related to a message on EC.
no problem... see bug #6720. I should be able to reproduce it, once I get hold of this mail api.
*** Bug 6788 has been marked as a duplicate of this bug. ***
I reproduced it. Duh, the search engine is returning anonymous types!
workaround in > 20011211 This bug remains open until the issue with #6839 is cleared.
subject: java.lang.StringIndexOutOfBoundsException: type name was empty I am a bit confused. The bug I intended to add my comments to is marked as duplicated to this one, but I don't see too much similarities. Still I believe the "trust me" stated below. Anyway. With the stable build as of 20011206 I get an error dialog when opening the type browser CTRL+SHIFT+T when (trying to) use it on a big project, i.e. with many libraries. I just try to open it, but even before the input dialog appears I get the error dialog. Below I pasted the data from the log.

As stated above, it has been fixed with a workaround in 20011211. The only reason this bug is still open is because it depends on 6839. Once that is fixed, I will be able to remove the workaround and mark this bug finally as fixed.
fixed > 20020207 finally removed workaround.
