Upgrade to the recently release Checkstyle 5.6.
Note that Checkstyle 5.6 removes the Double Checked
Locking check module, so existing Checkstyle configurations must be adapted.
Other changes:
The plugins internal handling of extension plugins has been changed to not rely on
buddy-classloading anymore. Immediate action from extension providers is not required since the old way of
intergration still works. However, certain usecases (providing custom quickfixes) only work with the new way of
setup.
Please check out the updated docs here . The sample extension project
in CVS has been updated as well.
I have given the plugin a short spin on the "new" Juno release of Eclipse (4.2), which seemed to work fine
so far.
