Subject [jira] Commented: (BVAL-72) NPE when doing methodvalidation
Date Tue, 29 Jun 2010 22:56:50 GMT

    [ https://issues.apache.org/jira/browse/BVAL-72?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12883742#action_12883742

Carlos Vara commented on BVAL-72:
---------------------------------

Hi David,

I can't replicate the issue with a simple standalone test involving a method declared in an
interface, so I think it's very likely related to Spring's dynamic proxies. Looking at your
stacktrace, you are running a junit test, could you please attach it to the issue?
