This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
I observed the following situation. I had some PATH elements that were unreachable. I launched Netbeans with CND; I didn't open any project and just closed Netbeans. I noticed that the process does not finish for minutes. The stack shows that it is CompilerSetManager who performs file IO. I'd like to mention that in this case I had only installed CND, I wasn't going to work with C/C++ code at all, so it's quite natural to not have compilers in my path.

The CompilerSetManager was being initialized during closure because it had not been previously. Since its closing, there is nothing to be gained by initializing it. I've changed it so it only executes the closure code if its already been initialized.
