jamvm 1.5.1-3ubuntu0.1 (amd64 binary) in ubuntu intrepid

 JamVM is a new Java Virtual Machine which conforms to the JVM
 specification version 2 (blue book). In comparison to most other
 VM's (free and commercial) it is extremely small, with a stripped
 executable on PowerPC of only ~110K, and Intel 80K. However, unlike
 other small VMs (e.g. KVM) it is designed to support the full
 specification, and includes support for object finalisation, the
 Java Native Interface (JNI) and the Reflection API.
