Description Kim Moir CLA 2011-02-01 10:50:55 EST 
I ran a test build yesterday, and noticed test failures on the windows 7 slave machine for jdtui. Do you know why these would occur?  (I don't have access to the machine to look at it other than the logs it produces)

(look for jdt ui in the test failure messages)  

For example

Markus, please check on your Windows 7 machine.
Comment 2 Markus Keller CLA 2011-02-01 14:10:48 EST 
I can't reproduce this in my workspace, and I don't really understand how this could happen. The tests fail because java.io.File#mkdirs() didn't create the folder "DummyProject" on the file system (right below the workspace root).

The best "explanation" I can come up with would be that someone else was messing around with the workspace while the tests were running.
Comment 3 Kim Moir CLA 2011-02-01 14:22:46 EST 
Thanks for checking Markus.

The machine resides at an ISP so I don't think there are issues with the people messing with the filesystem :-)  We are the only team that uses this machine.    I'll run the tests again.

They passed on the test build we ran on the weekend.
