Description mienamoo 2011-11-29 09:38:12 UTC 
NetBeans IDE 7.1 RC1 (Build 201111242103)
JDK 7 build 147

Making a copy of a class in the same package as the original (and refactoring) sometimes does not complete. I am able to replicate the issue, but the cause seems very vague. So I am providing as much information as possible in the hope that it will narrow it down somewhat.

1. I had a number of NetBeans platform modules open. All of the modules are version controlled using SVN.
2. Ctrl+drag a class in a unit test package of one of the modules to make a copy.
3. Click refactor.
4. The process seems to never complete, so I cancelled it.
5. Then I switched to another project group, to see whether I can reproduce the issue. In the newly opened project group, I had a few non-version controlled suites and modules.
6. The same thing happened for a class in a source package of one of the modules and I cancelled again.
7. Then I switched back and forth between the project groups and at some point got the following error message:

Cannot rename file TestClass1111_1.java in C:/Users/user/Documents/NetBeansProjects/Suite/Hallo/src/a to TestClass11111.java.

8. The class did exist, with the file contents (class name) and the file name not corresponding.

I am now running 7.1.1, after the update test that we did last week. And I was luckily able to replicate the problem quite easily. Log attached as requested. :)

In this case I created a new suite with one new module in it containing a single class. And restarted the IDE so that the log contains only the relevant stuff. I tried to copy the class, and the process didn't complete. While I was waiting, lines 503 to 533 got logged. 

So I cancelled and tried again. And then the rest of the lines got logged. The second time it did complete, but I ended up with two classes. A file called NewClass_1.java containing a class named NewClass1 (note the discrepancy!) and another called NewClass_2.java (correct class name).

probably windows specific.
Comment 6 mienamoo 2012-04-17 10:03:31 UTC 
Could indeed be.

Today I have seen al kinds of weird behaviour and exceptions with the refactoring, but only after running the IDE (build 201204150400) for a few hours. I am starting to think that these things happen when the heap is getting full. I haven't been able to reproduce the exceptions since restarting the IDE. :)

Unable to reproduce and last occurred in 7.2. Resolving as worksforme.
