Subject [jira] [Commented] (BEANUTILS-492) IndexedPropertyDescriptor not supported for List in Java 8
Date Mon, 12 Sep 2016 14:10:20 GMT

    [ https://issues.apache.org/jira/browse/BEANUTILS-492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15484219#comment-15484219
] 

Stian Soiland-Reyes commented on BEANUTILS-492:
-----------------------------------------------

I've added documentation to getPropertyDescriptor()

What about getPropertyType()?  It will return List in Java 8 rather than the leaf-type String
in Java 6 (which presumably did a heuristic guess by the first element).
