[eclipse-dev] Intermittent test failures on Windows - Make sure you clos

[Francis Upton <francisu@xxxxxxxx>]

On Windows some of the tests fail sometimes with an exception trying to 
close a resource.

This is caused by the file still being open.  Windows (unlike Linux or 
the Mac) will not let you close a file that it is still open.  However, 
this sometimes works, because a garbage collection will close the file 
for you (provided the stream is no longer referenced).

If you get this error, make sure the stream associated with the file has 
been properly closed.

Here is an example of a previously fixed problem:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=244610

Other causes of intermittent problems on windows have to do with 
deleting and renaming.  Windows has issues that other platforms don't 
have with the Java delete/rename.

For delete/rename to work reliably you have to check that it actually 
worked and try again (possibly a few times, after a small delay) to 
until it works.  There is probably some common code somewhere that does 
this.  See Sun/Java bug #6213298.

If these issues are addressed, it should greatly reduce the number of 
intermittent failures on Windows.


Best,
Francis
