Checkstyle Eclipse plugin doesn't work

Question

I'm using eclipse checkstyle plugin with Juno Eclipse distribution. Anytime the code is checked for checkstyle error I get the following error:

cannot initialize module TreeWalker - Unable to instantiate DoubleCheckedLocking

Does anybody know how to fix this problem? Is it a plugin compatibility issue or something else?

The DoubleCheckedLocking check has been removed in Checkstyle 5.6 and must be manually removed from your Checkstyle configuration.

How can I remove DoubleCheckedLocking configuration? – Alex Objelean Oct 09 '12 at 11:17

Editing the checkstyle configuration file using a plain text editor iss the way to go. The location of this file should be visible in the checkstyle configuration page in your eclipse checkstyle settings. – Torsten Oct 09 '12 at 11:23

Open the Checkstyle preferences, create your own Check Configuration, go into your own check configuration, find the TreeWalker module, click it and then un-check the DoubleCheckedLocking. As simple as that.

Under your Eclipse Workspace Search for file internal_config__*.xml
Remove the following line from the file

<module name="DoubleCheckedLocking"/>
Reload Workspace.

This will work for any discontinued module which produces the error message "Unable to instantiate"
