Choice Exception Strategy doesn't work in Mule - exception

Question

Below is a exception strategy part of the flow
<choice-exception-strategy doc:name="Choice Exception Strategy">
<catch-exception-strategy when="exception.causedBy(java.sql.BatchUpdateException)" doc:name="SQL deadlock error">
<logger message="SQL EXCEPTION - RETRYING BATCH PROCESS"
level="ERROR" doc:name="Payload Logger" category="asi_user"/>
<set-variable variableName="Exception" value="User" doc:name="Exception Type"/>
<flow-ref name="Reload_Batch" doc:name="Retry Batch Results"/>
</catch-exception-strategy>
<catch-exception-strategy when="exception.causedBy(com.microsoft.sqlserver.jdbc.SQLServerException)" doc:name="SQL error">
<logger message="SQL EXCEPTION - RETRYING BATCH PROCESS"
level="ERROR" category="asi_user" doc:name="Payload Logger" />
<set-variable variableName="Exception" value="User" doc:name="Exception Type"/>
<flow-ref name="Reload_Batch" doc:name="Retry Batch Results"/>
</catch-exception-strategy>
<catch-exception-strategy doc:name="Unexpected errors">
<logger message="UNEXPECTED EXCEPTION - SEND EMAIL NOTIFICATION"
level="ERROR" category="asi_user" doc:name="Payload Logger" />
<set-payload value="#[exception.cause.message]" doc:name="Set Payload"/>
<flow-ref name="Send_Error_Notification" doc:name="Send Email Notification"/>
</catch-exception-strategy>
</choice-exception-strategy>
Even when a java.sql.BatchUpdateException is thrown from the flow, the control goes to the final exception strategy "Unexpected Errors", it doesn't go to SQL deadlock error
Am I missing anything to make it work.
Could any please help me with this to make it work.I'm using is Mule server 3.4.0 EE
Thank you in advance

Answer 1

It is the problem with your expression in the when
Try it the following way.
<catch-exception-strategy when="#[exception.causedBy(java.sql.BatchUpdateException)]" doc:name="SQL deadlock error">
Hope this helps.
