Hornet is a Java virtual machine designed for low latency, high performance applications.

• Multiple backends:
  • Interpreter
  • DynASM (x86-64)
  • LLVM
• Uses OpenJDK for standard class libraries
• Written in C++11
• Runs on Linux and Darwin

• Pauseless GC
• LLVM ahead-of-compilation
• RTJS class library support

First, install dependencies:

Fedora

$ yum install clang java-1.7.0-openjdk-devel

If you want to enable the DynASM backend, install LuaJIT:

$ yum install luajit

If you want to enable the LLVM backend, install the library:

$ yum install llvm-dev

Finally, install Hornet:

$ make install

The command installs an executable hornet to $HOME/bin.

Hornet works like java:

$ hornet
