Eclipse listens on port 42540 (?)

Question

I just appalledly realized my Eclipse IDE listens on port 42540. During the past weeks I installed some more or less useful plug-ins (and removed some of them). Maybe one of them listens on this port, but I don't think/hope so. Currently, the following plug-ins are installed:

• Eclipse Color Theme 0.11.0.201104281646 com.github.eclipsecolortheme.feature.feature.group
• Eclipse IDE for Javascript Developers 1.3.2.20110218-0812 epp.package.javascript
• FontsFeature 1.0.4 FontsFeature.feature.group
• PyDev for Eclipse 2.0.0.2011040403 org.python.pydev.feature.feature.group
• Pydev Mylyn Integration 0.3.0 org.python.pydev.mylyn.feature.feature.group

Eclipse does not answer HTTP requests on port 42540. Is listening on port 42540 an intended behavior? How can I stop Eclipse listening on this port?

Sorry for being paranoid.

Answer 1

I had the same problem / concern. The port went away after I uninstalled a plugin we have in common - PyDev for Eclipse.

I reinstalled PyDev without PyDev Mylyn Integration. Eclipse is still not listening on a random high-numbered port. So it seems the Mylyn integration portion of PyDev is responsible for the open port.

Answer 2

I assume, that it is the built-in Jetty instance (a Webserver) for the Eclipse help system, even if it doesn't answer HTTP requests from a normal webbrowser.
