investigating ...

Comment 4 Jan Chalupa 2001-11-27 15:41:37 UTC

Target milestone -> 3.3.1.

Comment 5 Vitezslav Stejskal 2001-11-27 17:13:28 UTC

It occured when locks guard failed on SystemFileSystem. It could 
happen in case the only existing delegate of some MultiFileObject was 
on read-only layer (e.g. module's XML layer), in that case MFO.lock () 
does lock actualy nothing and locks guard failed leaving the project 
layer to be switched. This obsoletes FileLock obtained before the 
project layer is switched and results in exception when the lock is 
used with new project layer.

Fixed in release33 branch.

Comment 8 Quality Engineering 2003-07-01 14:17:38 UTC
