org.hibernate.type.EnumType is full of such logging:
LOG.tracev( "Returning '{0}' as column {1}", name, names[0] );

This leads to the following output:
[EnumType] [TRACE]: Binding {0} to parameter: 1

Excepcted:
[EnumType] [TRACE]: Binding VALUE to parameter: 1

Possible fix, change to
LOG.tracev( "Returning {0} as column {1}", name, names[0] );
