[jboss-jira] [JBoss JIRA] Commented: (JBRULES-3118) Parser: import of class with "enum" in the FQN fails to parse

    [ https://issues.jboss.org/browse/JBRULES-3118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12612652#comment-12612652 ] 

Edson Tirelli commented on JBRULES-3118:
----------------------------------------

"enum" is a reserved keyword in Java 1.5+, so you can't define a package name that contains it.

http://commons.apache.org/lang/api-2.3/org/apache/commons/lang/enum/Enum.html

"Deprecated. Replaced by org.apache.commons.lang.enums.Enum and will be removed in version 3.0. All classes in this package are deprecated and repackaged to org.apache.commons.lang.enums since enum is a Java 1.5 keyword."

I don't think there is anything we can (should) do here, as this is a Java compilation error, not a drools compilation error.
