A quick FYI. JamVM is definitely not dead! I'm still actively
developing/maintaining it (I'm the sole developer, and have been for over 10
years - Pekka Enberg forked JamVM at one point but abandoned it and moved
onto Jato as I wouldn't relicense JamVM under LGPL - I wanted to keep it GPL).
What is pretty much dead is GNU Classpath. This was the original class
library used with JamVM, but GNU Classpath development stopped once Sun's
Java was open-sourced as OpenJDK (IcedTea is a build harness for OpenJDK,
which originally replaced encumbered code with open-source alternatives).
JamVM still supports GNU Classpath, but active development is now part of
IcedTea, where JamVM is built as an alternative VM to HotSpot (the
Sun/Oracle VM). So you have Sun/Oracle's class library running on JamVM.
This is useful on embedded systems as it uses less memory, and it also
supports more architectures than HotSpot (ARM, MIPS, PowerPC, etc.).
