[jira] Updated: (LANG-597) Add more utility methods for generic types

     [ https://issues.apache.org/jira/browse/LANG-597?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Sledge updated LANG-597:
------------------------------

    Attachment: TypeUtilsTest.java
                TypeUtils.java

Proposed utilities (including a re-factored version of the one already present) and (what I hope are) extensive jUnit tests.
