Dennis Lundberg commented on MCHECKSTYLE-189:
---------------------------------------------
Hi,
My point on this, as a Maven developer and a Checkstyle user, is that the
Checkstyle project should not have removed a check in a minor release.
All Checkstyle configuration files that are included in Maven Checkstyle Plugin
was updated in version 2.10, so that they do not include the
DoubleCheckedLocking check. Only users that have their own configuration file
are affected.
The release log for Maven Checkstyle Plugin mentions that it has upgraded to
Checkstyle 5.6. We never include items from the Checkstyle project's release
log in ours. Interested users should check the Checkstyle project for that.
Yes, we could have made the plugin version 3.0, but we didn't. This can of
course be debated, but will not change the past.
