Metro and jsr173_api.jar vs stax.jar

We just tried to install metro 2.1 on tomcat 6.0.35 and it failed. One thing I'm seeing in the metro-on-tomcat.xml files is several references to jsr173_api.jar however no such file exists in the current download. However, stax-api.jar does exist. Should metro-on-tomcat.xml be changed to reference stax-api.jar in place of jsr173_api.jar ? Should that be the only change required?

Thanks,

Kris
