Subject [jira] [Commented] (CAMEL-6481) Can't access to length of Array (java) from simple language
Date Mon, 24 Jun 2013 17:00:22 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-6481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13692142#comment-13692142

Claus Ibsen commented on CAMEL-6481:
------------------------------------

This is working as designed. length is not a method, but a field on an array.
