Incompatible initial and maximum heap sizes specified

[johnnyCash]

Have just tried to install MAVEN 2.1.0 and set all my system variables. Every different version of MAVEN_OPTS results in ...

C:\Users\John>mvn --version
Error occurred during initialization of VM
Incompatible initial and maximum heap sizes specified

It is currently a user variable ...
MAVEN_OPTS=-Xms256m -Xmx512m

Any ideas?

[javabrett]

Google finds a number of Sun JDK bugs for this error message - which
JDK/version are you using?

As a workaround, try setting -Xms and -Xmx to the same value if you can
tolerate that setting.

That may need to be in quotes.... MAVEN_OPTS="-Xms ... -Xmx ..."
