Launching

What is contextual launching?

Contextual launching is a new, simpler way of launching in Eclipse built using all of the familiar launching metaphors.

In the traditional launching mode, Eclipse would simply launch the last thing that was was launched. With context launching, what gets launched is determined by what the current selection in the workbench is. For example, if you have a Java file with a main method open in the editor, pressing "run" (or debug) will launch it as a Java application. Even if you have not created or know how to create a launch configuration for the launch, the context launching framework will create one for you (which you can edit at any time via the launch configuration dialog).

Context launching is the default method for launching in 3.3 M7 builds and later.

For interests sake there is more information in this paper on context launching.

How do I turn off contextual launching?

If you just can't get over the old way of doing things, you can do so on the Run/Debug > Launching Preference Page. Change the Launch Operation option to "Always launch the previously launched application".

Variables View

How do I fix an IllegalArgumentException coming from the Variable View's SashForm?

This was fixed in 3.3. An invalid value is stored in the view's memento. You can clear out this value by clearing your workspace preferences, or opening <workspace loc>\.metadata\.plugins\org.eclipse.core.runtime\.settings\org.eclipse.debug.ui.prefs and changing SASH_DETAILS_PART to a value of 6 and SASH_VIEW_PART to a value of 13. See Bug 199385 for more information.

Console

Why does Eclipse sometimes hang when a lot of output is written to the console?

If you are writing a large amount of data to the Console streams from the UI thread, the console will be unable to clear the buffer. See Bug 136943
