[jira] [Created] (NETBEANS-3688) NPE when Debugging using FlatLaf

Laszlo Kishalmi created NETBEANS-3688:
-----------------------------------------

             Summary: NPE when Debugging using FlatLaf
                 Key: NETBEANS-3688
                 URL: https://issues.apache.org/jira/browse/NETBEANS-3688
             Project: NetBeans
          Issue Type: Bug
            Reporter: Laszlo Kishalmi
            Assignee: Karl Tauber


During my recent tests it seems, setting up the debugger view using FlatLaf results a NPE.

It happens as [DebuggerViewComponent.getTreeBackground()|https://github.com/apache/netbeans/blob/c5cffaca24a64550209f7acfb636311fc0b51b2b/ide/spi.debugger.ui/src/org/netbeans/modules/debugger/ui/views/debugging/DebuggingViewComponent.java#L339] gives back null on FlatLaf.

It is easily fixable by adding: *Tree.textBackground=@background* to the FlatLaf.properties, however the usage of the getTreeBackground() method is a bit suspicious to me, so I'd like if a LaF expert could look at that.
