Marek Novotny commented on JBSEAM-4856:
---------------------------------------
Todd, even it seems odd that Seam 2 doesn't support parallel init of multiple
war in EAR, it is the reality. Seam 2 is in process of upgrading JSF2,JPA2
integrations, but for full isolation of web application in EAR it is too much
for minor version.
You can raise such a feature, but this won't have any high priority for us. So
if a community developer would like and provide patch for that, I will happily
apply that.
