Java-level JVM compiler interface [JEP-243]

The JEP-243 was to create a Java-based JVM Compiler Interface (JVMCI). The JVMCI enables a Java compiler (which must have been written in Java) to be used as a dynamic compiler by the JVM.

The reasoning behind the desire for the JVMCI is that it would be a highly optimized compiler that does not require low-level language features. Some JVM subsystems require low-level functionality, such as with garbage collection and bytemode interpretation. So, the JVMCI was written in Java instead of C or C++. This provides the collateral benefit of some of Java's greatest features, such as the following ones:

  • Exception handling
  • IDEs that are both free and robust
  • Memory management
  • Runtime extensibility
  • Synchronization ...
