Trove is a dependency for AS, but its license which should be packaged for legal reasons is not pulled in by the build.

<dependency>
<groupId>trove</groupId>
<artifactId>trove</artifactId>
<version>1.0.2</version>
</dependency>

License exists here: http://repository.jboss.org/licenses/trove.txt

The release build packages all licenses under thirdparty/licenses. This should also contain the license for trove.
