Possibly caused by network (slow or even broken) file access called from maven project action.

Opened a context menu of a project node (in Projects). That project is a Maven project stored in a Clear Case VOB accessed using a CC dynamic view.

This happens every time.

Wasn't that slow in 6.8.

Reassigning to default owner.

Comment 5 Antonin Nebuzelsky 2010-09-24 12:50:49 UTC

All snapshots show the time is spent in java.io.WinNTFileSystem calls. Number of calls is not huge, just a few tens of them, but summed up they take the tens of seconds. I don't see a way to fix that because it is most probably caused by temporarily overloaded system filesystem.

puppala, please provide more information if you can. Where is your project stored (type of filesystem, latency of I/O on the network if it is on a network FS)? Is some other process on your machine doing intensive I/O at the time you see the problem?

Comment 6 puppala 2010-10-04 12:42:47 UTC

As I said, the project is a Maven 2 project stored in a Clear Case VOB. The Clear Case is a distributed one, so it is accessed via network. And yes, it sometimes causes access problems also outside NetBeans.

It would be interesting to know, what kind of file operations this case includes ? Sometimes in our environment it takes many seconds to e.g. right click a file in Clear Case Explorer.
