Known Issues and Limitations

WSO2 ESB known issues and limitations
- ESBJAVA-509 Unwanted Java Script alert displayed when updating the Cache Mediator
- ESBJAVA-444 Problem when creating an endpoint from a WSDL and the address of the WSDL is a https address
- ESBJAVA-452 Once a Proxy Service is removed the relevant statistics of that particular Proxy service should be removed as well
- ESBJAVA-484 ESB fails to start when WSDL URI is not found
- ESBJAVA-497 VFSTransportListener Error closing stream
- ESBJAVA-346 Cursor not available in some of the popup windows
- ESBJAVA-372 [IE] When the wso2-esb.log is about 2MB .. the browser hangs
- ESBJAVA-505 Problems with web console in Firefox 3.0 RC1
As the WSO2 ESB 1.7.1 depends on the Apache Synapse ESB v1.2, it inherits the list of known issues of the Apache Synapse ESB 1.2 release listed below
- SYNAPSE-180 Does not support throttling by concurrency within a cluster
- SYNAPSE-186 Does not support HTTP some of the REST operations (such as put/delete etc)
- SYNAPSE-181 Does not yet support JTA transactions
- SYNAPSE-330 Does not yet support load balancing with session affinity using SOAP sessions
- SYNAPSE-280 Does not preserve CDATA sections within payloads
- SYNAPSE-307 The XSLT mediator will not report errors encountered in a provided stylesheet
- SYNAPSE-348 MTOM serialization of attachment fails
- The Synapse JMS implementation supports JMS 1.0.2b, however due to licensing issues we include the JMS 1.1 spec JAR from Apache Geronimo (geronimo-jms_1.1_spec-1.1.jar) instead. If you have any issues with JMS 1.0.x, please download the Sun JMS 1.0.2b JAR and replace supplied JAR from Geronimo.
Dependencies are currently allowed to be removed from the admin console, while live references remains
- The ESB UI currently does not perform a check on references before the elements are allowed to be removed. Thus there is a possibility of defining references to non-existent endpoints, sequences etc. as well as removing them while live references still exist.
