Hi Indy,
For the first error, replace your ""null_AD_CMSG_java"" with "Market setting not configured". The field will contain no quotes when you save the rule.
For the second error, remove the quotes around "String index out of range" so the field contains no quotes when you save the rule.
Note the behavior of this configuration "When you configure an exception to be ignored, the agent detects the exception, increments the exception count, and displays the exception in Exceptions lists in the UI, but the business transaction in which the error is thrown is not considered an "error transaction" for monitoring purposes. The transaction snapshot would not show the exception in the Summary or Error Details section and the user experience for the transaction instance would be unaffected by the exception." https://docs.appdynamics.com/display/PRO42/Configure+Error+Detection
In other words, AppDynamics will continue to detect and monitor the exception, but the user experience of the request in which this exception occurs won't be marked as "Error" and the exception won't appear in the associated diagnostic snapshots.
Regards,
Brian Wheeldon
