Javaw.exe - Approximately 60 Instances Running Simultaneously

Question

Upon checking Task Manager (Windows 7), I have approximately 60 instances of javaw.exe running, ranging from approx. 1,000K - 450,000K.

I am currently working on a large project, developing some software using Eclipse Helios.

Can somebody explain why this is happening?

Answer 1

Lots of possible reasons for this, but in my experience the most likely is that instances of your app that you are starting to test or debug are staying around after you think they are gone.

Answer 2

If you don't explicitly stop the previous instance, and click the "Run As" (Green Arrow) button again, the previous instance will just keep running in the background. In the console tab, there is a drop down which will show all running instances. You need to click the red box on each of these to kill the process.

Answer 3

I think it's a bug in Eclipse. When you stop the console - clicking the big red button - the javaw.exe process carries on running.

You solve it by opening task manager, identifying the javaw.exe process that isn't for Eclipse (go to show columns and show "command line") and then right click: end task
