[jira] [Commented] (CAMEL-5060) camel-bam is not thread safe and
throws ConcurrentModificationException
[ https://issues.apache.org/jira/browse/CAMEL-5060?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13251388#comment-13251388 ]
Claus Ibsen commented on CAMEL-5060:
------------------------------------
Christian do you have a test to reproduce the issue?
I ran camel-bam test and looked in the logs and no exception was thrown.
The fix could just be to use a ConcurrentMap, but would like a test to verify as well.
