Description Tim Lebedkov 2010-05-30 09:24:21 UTC 
I have an action in GWT4NB that changes libraries in a project and I get this exception very often:

SEVERE [org.openide.util.Exceptions]

Caused: org.netbeans.modules.masterfs.filebasedfs.utils.FSException: Cannot get exclusive access to C:\Users\t\Documents\NetBeansProjects\WebApplication4\nbproject\project.properties (probably opened for reading).
