Question: "Does it work on Linux?"
clock@kestrel:~$ java -classpath
*** glibc detected *** free(): invalid next size (fast): 0x08059d88 ***

Answer: "No."

I was once impressed by slowness of Java. A game "Jet Set Willy" for ZX
Spectrum was emulated in Java - it ran on maximum speed on pipelined
32-bit CPU with 1800MHz clock as fast as original machine code version
ran on 8-bit CPU with 3.5MHz clock where fastest instruction took 4
cycles.

Java is a great tool if you want to destroy planet by meaningless
manufacture of high-power CPU's and then wasting their CPU time and
scarce energy. Not a great tool of you want to run a program.
