Membar issue i386 specific?

[Will Saxon]

Hello,

Is the SIGBUS issue requiring the use of -XX:+UseMembar i386 specific? I
was positive that I had used this option before on an amd64 machine but
today when I went to edit my /usr/local/bin/javavm script (per a prior
post by Greg Lewis) and tried to execute a java program I received the
following error:

	Unrecognized VM option '+UseMembar'
	Could not create the Java virtual machine.

I verified that this occurs when passed on the command line also.
