Maven is executed in a different way in TC 6.5.x

Hi,

I noticed maven is being executed in a different way in TeamCity 6.5.x than 6.0.3?

Here is the build log from 6.0.3:

Starting: sh /opt/packages/teamcity/plugins/maven/bin/mvn

Here is the build log from 6.5.1

Starting: /usr/java/jdk1.6.0_22/bin/java -Dagent.home.dir=/opt/packages/teamcity .....

Does this have any impact on setting MAVEN_OPTS as we are now having PermGen failures after upgrading?  It doesn't seem like the MAVEN_OPTS settings are being used in the maven execution now.

Any help would be great.

Thanks,
Jay
