JDK Mission Control (JMC) 9.1.0 introduces several enhancements that significantly improve Java development, particularly in the areas of performance monitoring, profiling, and troubleshooting. Here are the key improvements:

Performance Enhancements

• Improved JFR Parser Performance: The parser's performance has been enhanced through reduced allocations, leading to faster processing of Java Flight Recorder (JFR) data. This includes optimizations such as a reduction in the allocation rate and improved search capabilities within the parser.

• Java-Based Flamegraph Visualization: A new Java Swing-based framework has been implemented for flamegraph visualization, enhancing both performance and efficiency. This allows developers to better analyze application performance visually.

New Features

• Custom JFR Event Types: JMC 9.1.0 allows developers to use custom JFR event types by extending the jdk.jfr.Event class. This capability enables more tailored profiling and
