Description John Pitman CLA 2008-06-25 14:04:46 EDT 
Build ID: 3.4 RC4

Steps To Reproduce:
We have some code that creates an new source folder as part of creating a WTP project.  Due to threading issues in JavaProject.resolveClasspath(PerProjectInfo), this change to the project's classpath is getting lost.

At the start of the resolveClasspath method, it makes a copy of the projects raw classpath, and at the end, it calls perProjectInfo.setClasspath() with that copy.

The problem we are seeing is that after resolveClasspath has made its copy, a second thread executes which updates the project's classpath, and then execution swithces back  to the resolveClasspath on the first thread, which calls perProjectInfo.setClasspath() with the stale copy of the raw classpath, wiping out the change.

I added some trace statements to the start and end of JavaProject.resolveClasspath() which print out the value of the saved raw classpath, and to perProjectInfo.setClasspath() which prints out the newRawClasspath passed to it, to show this this happening.

Since resolveClasspath gets invoked recursively, the number in brackets indicates the recursive depth.
