[jira] [Commented] (CAMEL-11235) Simple Language: Set#size fails
with AmbiguousMethodCallException
[ https://issues.apache.org/jira/browse/CAMEL-11235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16000377#comment-16000377 ]
Pascal Schumacher commented on CAMEL-11235:
-------------------------------------------
As a workaround I tried to use this simple expression:
{code}${headers.materialnumbers.isEmpty()} != true}
This fails with:
