It seems that the problem is caused by Tika library which has not been compiled for Java 6. There seems to be no upgrade in community BOMs, but the product uses a productized version of this library 1.3.0.redhat-1, so it might be an issue with the productized artifact only.

This is a regression from 6.4.0 ER1.
