[jboss-jira] [JBoss JIRA] Updated: (JBRULES-1820) Exception: Input stream is not explicitly closed.

[Mark Proctor (JIRA)]

     [ https://jira.jboss.org/browse/JBRULES-1820?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mark Proctor updated JBRULES-1820:
----------------------------------

    Fix Version/s: 5.2.0.M1
                       (was: 4.0.8)


These issues where all marked for 4.0.8, we no longer maintain the 4.0.x branch in the community. I'm moving them to 5.2.0.M2, so they can be checked that they no longer cause a problem there, and fixed if they do. If you require these fixed at the 4.0.x branch level, then please contact sales at jboss.com for subscription based support.

> I am using the Drools PackageBuilder to create business rules from a file. While the rules appear to function correctly, when the JVM which runs the application shuts down, an exception is thrown due to the forced closing of an unclosed stream. It looks from the stack trace like the Drools code is opening a stream using ClassLoader.getResourceAsStream which is then left unclosed and is forced close at JVM shutdown.
> On application server shutdown, I receive the following exception. This appears to be the result of an unclosed input stream for a system resource used by the Drools compiler.
