note full stack trace of root cause available in jboss web/7.0.13.final logs.

what should do? using jboss 7.1.1 final on windows 7 x64.

thanks.

a workaround fix included in sesame deal issue, avaiable in upcoming release. however, pointed out on mailinglist (see comment), sesame 2.7 has deprecated mysql store. recommend switch different storage backend (such native store).
