propertyset.jar!/WEB-INF/persistence.xml is missing <jta-data-source> definition

While deploying on JBoss:

Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a jta-data-source for a JTA enabled persistence context named: propertyset

Are users supposed to explode `jira.war/WEB-INF/lib/propertyset-1.5.jar`, edit it's `/META-INF/persistence.xml`, re-pack and deploy the result? With every Jira upgrade?
