Safety First: Enhancing JVM Performance and Security

Safety First: Enhancing JVM Performance and Security

Explore the intricacies of JVM safety and performance optimization in this 39-minute conference talk from the 2015 JVM Language Summit. Delve into topics such as array bounds checks, variable handles, and signature polymorphic methods. Learn about the replacement strategy for unsafe operations, performance results, and potential future vectorization. Gain insights into the goals of variable handles, their types, and access modes. Examine the implementation of lookup invocation and invokeExact methods. Discover how VarHandles can be used with bounds checks and in exotic scenarios. Understand the current situation of JVM safety and the near-term focus for improvements.
