Re: [Htmlunit-user] Specifying which UserProfile on Netscape and Mozilla

[<ddk...@ki...>]

You need a trailing "m" to specify megabytes, but you can't just specify
this option.  You need additional parameters (like -version):

  $ java -Xmx512m -version
  java version "1.4.2_06"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_06-b03)
  Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)

Note what happens if you add a space:

  $ java -Xmx 256m -version
  Invalid maximum heap size: -Xmx
  Could not create the Java virtual machine.
