JPPF 6.2 beta preview release

on GitHub

Major refactoring of the management and monitoring MBeans

• the node forwarding MBean now provides compile-time typing of the results
• all built-in MBeans are annotated with metadata available at runtime
• the same metadata is used to generate static forwarding proxies (and their unit tests) for the built-in node MBeans
• the MBeans metadata is also used to generate the built-in MBeans reference documentation
• the management and monitoring documentation was refactored for greater clarity and readability

Administration and monitoring console improvements

• numerous performance hotspots were identified and fixed, both in the monitoring API and in the UI rendering code
• for license compatibility reasons, the JFreeChart charting library was replaced with XCharts, resulting in further performance improvements

Performance improvements in the driver and JMX remote connector

Several performance sinks were identified and fixed, in high stress scenarios where a very large number of job lifecyclle notifications were generated, causing high spikes in CPU and memory usage.
