One of my plugin's users reported this to me. Basically I have a custom tool window that renders the results of a query into a JTable. Traditionally users have been able to copy the table cell contents using standard CTRL+C/CMD+C for paste into other applications. This is using JTable's standard clipboard support, not anything I added explicitly. This still works fine in Windows IDEA 15, but I've verified that in Mac IDEA 15, copy/paste from JTables no longer works. Any idea why this might be and what I might do to restore this behavior for the users?
UPDATE: Actually one of the tables is a JBTable and another is a JTable. I see the same behavior in both.
