[jira] [Commented] (CAMEL-8785) StackOverFlowError using Custom InterceptStrategy

["Willem Jiang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-8785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14553564#comment-14553564 ] 

Willem Jiang commented on CAMEL-8785:
-------------------------------------

As the Custom InterceptStrategy could introduce a cycle to processor chain, that lead to the StackOverFlowError.
We need to avoid this cycle when setup the InterceptorToAsyncProcessorBridge.
