Known Issues and Limitations

1. WSO2 ESB known issues and limitations
   • ESBJAVA-234 - After clicking on the "Close" button of the "Sequence Editor" window when adding anonymous sequences to a Proxy Service, the mediators lost the next time you open the "Sequence Editor" window
   • ESBJAVA-351 - The average response time of "Server Statics" displayed as NaN under some instances
   • ESBJAVA-268 - Unable to start the sample axis2server.bat on Windows
   • ESBJAVA-373 - [IE] When the wso2-esb.log is about 2MB and when trying to access System logs using IE, the browser hangs and the CPU usage goes upto about 50%
   • ESBJAVA-309 - Unable to view/edit the sequences after clicking on the "Close" icon of the WSO2 ESB Sequence Editor window of a sequence in the Integrated Registry
   • ESBJAVA-408 - Support improved renaming of files in VFS transport
2. As the WSO2 ESB 1.6 depends on the Apache Synapse 1.1.1, it inherits the list of known issues of the Apache Synapse 1.1.1 release listed below
   • SYNAPSE-180 - Require the ability to throttle by concurrency within a cluster
   • SYNAPSE-174 - The non-blocking http/s transports cannot handle WS-RM requests
   • SYNAPSE-213 - Improve handling of input in XSLTMediator
   • SYNAPSE-211 - Improve performance in XSLTMediator when temporary files are used
   • SYNAPSE-212 - XSLTMediator doesn't close/delete temporary files properly
   • 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.
3. 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.
