Build Identifier: I20100129-1300 Version: 3.6.0.v20100124-2000-7z8WFRAFMTdeCo0y7FJt1Zi45027 Duplicating a java class via copy/paste from package explorer fails with StringIndexOutOfBoundsException. Reproducible: Always Steps to Reproduce: From Package Explorer I select a java class that I want to duplicate. After CTL-C, CTL-V I can choose a new name in a dialog. After changing the proposed name to a new one and hitting OK, the following exception occurs. I could not reproduce this on a new java project with a single java class, so there is probably some dependency on the complexity of the class hierarchy. java.lang.StringIndexOutOfBoundsException:

In order to investigate, we would need a reproducable test case. If you can provide your workspace, that would definitely help.
Unfortunately, I can't reproduce it in a small case. I just tried again in my workspace and now I even can't reproduce it there anymore (the class has been refactored in the mean time but when I revert that the error still does not happen). You can't deduce from the stack trace in which situation this occurs? In that case i think the case can be closed as non-reproducable, maybe someone else has the same error and can send in the workspace. Rob
(In reply to comment #2) > You can't deduce from the stack trace in which situation this occurs? No, unfortunately. It just tells me that some buffer contents is inconsistent, but I cannot find out why from the stack trace. This would explain why it is difficult to reproduce. Closing as WORKSFORME for now. Don't hesitate to reopen if you can provide a test case.
I tried reproducing but could not reproduce. Verified for 3.6M6
Just got the same exception: Initial state: * Class with name "DateTimeDeserializer.java" Steps to reproduce: * Drag with mouse the class "DateTimeSerializer.java" with Ctrl pressed to the same package. "Name Conflict" resolution dialog appears. [OK] * Enter "DateTimeSerializer" and press OK.

The problem actually exists, it happened at least with two classes to me with Photon during the latest month. When you identify such cases, it happens always. Could you please reopen? Even if there's no test case, it's certainly a problem that affects users. The AERI also points here when the exception occurs.
This is happening quite often in 2021-12, almost every day I have to restart the IDE because of this problem.

org.eclipse.equinox.launcher.Main.main(Main.java:1440) The problem is not bound to the workspace, it happens some time after working with the IDE. Perhaps, something gets corrupted at a certain point and this problem starts to arise. After that point, you have no choice than restarting the IDE. I suspect this has to do with a timing issue somewhere, so it's probably easier to reproduce on a slow system, although I really have no idea on how it could be reproduced in a consistent way. It happens to me on different workspaces.
