Description _ tboudreau 2007-02-27 16:23:35 UTC

I accidentally added c:\space (the root of all sources on my laptop, including
two NetBeans checkouts) as a library dir to a J2SE project.  This started
classpath scanning (which will probably go on for a very long time - ideally it
should be abortable somehow).

I removed the directory as a library and added the JAR file I was actually
looking for.

Then I right clicked the project and chose Run.  The menu does not close and AWT
is blocked - apparantly in the code that checks if there is a main class. 
Probably it will unblock eventually, but not until scanning is complete, which
could be a very long time.

The J2SEActionProvider should use the runWhenScanFinished rather than runUserActionTask.

Comment 3 Tomas Zezula 2007-07-12 09:58:14 UTC

Caused by excludes. The ClassPath was changed to call ClassPathImplementation.getResources() in the SPIListener  (called
synchronously from the AWT). The getResources() may be expensive for GlobalSourcePath - it calls SFBQ which is slow. The
only thing which may help is to fire changes from GlobalSourcePath asynchronously - probably doesn't matter.
