Systems using Classpath: gcj

• GCJ uses its own class library (“libjava”)

  • Being merged with GNU Classpath
    • Some parts are tricky to merge (optimizations)
  • Non-standard interface for native code
    • “Compiled Native Interface” = C++
    • Support for standard JNI has been added, but JNI is slower than CNI (and much more verbose)
