Bill: What happens if I specify -Xmx multiple times on the command line?
Me: I don’t know, let’s find out.


java -Xms1024m -Xmx99999 -Xmx1024m -version
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-237)

java -Xms1024m -Xmx1024m -Xmx99999 -version

Me: The last one always wins.
