Created attachment 133149 [details] nps snapshot
This looks like font initialization - may take long sometimes if the system is busy (overloaded) with disk I/O intensive work. The attached snapshot shows the actual time is spent in I/O. This is invoked from layout computation - by calling simple JLabel.getPreferredSize(). We can do hardly anything with this. (Might try experimenting with doing this in some warm up, but for that we'd need somewhat more reports - this does not look like a frequent problem to deserve that.)
