Description Alexander Simon 2011-08-30 07:52:37 UTC

Some times project meta data of full remote project is broken.
Symptoms:
- nbproject/configurations.xml is empty or written partly.
- mirror of nbproject/configurations.xml is OK.
- after restarting IDE project is broken.

Root cause of such behavior is double closing of SmartOutputStream.
At first closing the class copy temporary local file to remote file object and delete temporary file.
At second closing SmartOutputStream counts check sum again and can decides to copy file again (because we have a races and check sum can be performed on partly written remote file). Second writing results in empty nbproject/configurations.xml because temporary file have been deleted.
