Michael Heuer commented on MCHECKSTYLE-189:
-------------------------------------------
Tar via cygwin should work on windows.
The problem is in fact with a custom configuration checkstyle.xml which
includes
{code:xml}
<module name="DoubleCheckedLocking"/>
{code}
The release notes for Checkstyle 5.5 --> 5.6 say
bq. Removed the DoubleCheckedLocking check, as in Java 5 (and beyond), using
the volatile keyword addresses the issue. See here for more details.
The release notes for Maven Checkstyle Plugin 2.9.1 --> 2.10 do not mention
this change.
I think both projects have failed with regards to semantic versioning -- even
though this is not a strict binary-incompatible change, it is a
configuration-incompatible change. Updating a minor version of a maven plugin
should not cause existing projects to break.
