Dump tab

This tab appears when the Dump button the Dump button is clicked on the Debugger toolbar, or on choosing Run | Debugging Actions | Get Thread Dump on the main menu.

Use this tab to review the external thread dump or the one taken from the debugger in a handy way. The tab is divided into two parts. The left one displays all threads, and the right one - the stack trace for the selected thread.

In the Dump tab, all threads are sorted so that the most meaningful and useful threads are on top of the list. For your convenience, threads are displayed in varying shades of gray text, and deadlocks are highlighted in red.
