Use of 'severity' attribute in module configuration file causes
UnsupportedOperationException
---------------------------------------------------------------------------------------------
Key: MNG-1846
URL: http://jira.codehaus.org/browse/MNG-1846
Project: Maven 2
Type: Bug
Components: maven-checkstyle-plugin
Versions: 2.0.2, 2.0
Environment: Windows XP, J2SDK 1.4.2_10, maven-checkstyle-plugin
2.0-beta-2-SNAPSHOT, Maven 2.0.2-SNAPSHOT
Reporter: Nick Giles
Attachments: trace.txt
When I provide the Checkstyle plugin with a customised config file, it causes
it to crash unpleasantly when generating the report. It appears that this is
due to calling the 'remove' method on Arrays$ArrayList, which doesn't implement
the method. The call is actually removing the 'severity' property from the list
of columns before going on to process the rest. Wrapping the list in an actual
ArrayList (java.util.ArrayList) solves the problem.
To replicate, add <configLocation>your-rules.xml</configLocation> to the plugin
configuration, and ensure that at least two modules in your-rules.xml have the
severity property set, something like:
<?xml version="1.0"?>
<!DOCTYPE module PUBLIC
"-//Puppy Crawl//DTD Check Configuration 1.2//EN"
"http://www.puppycrawl.com/dtds/configuration_1_2.dtd";>
<module name="Checker">
<module name="PackageHtml">
<property name="severity" value="warning" />
</module>
<module name="NewlineAtEndOfFile">
<property name="severity" value="info" />
</module>
</module>
