Message Title

I don't know if this is the same problem I am facing with 5.1.0 but mine is definitely also related to filters. We have implemented multi-tenancy within one schema using a discriminator clolumn with filters. This worked great with hibernate 4.x. Since the latest upgrade to 5.1.0 the filters' query parameters don't get set resulting in exceptions like the following:

if ( filters.size() == 0 || !sql.contains( ParserHelper.HQL_VARIABLE_PREFIX ) ) {
	// HELLA IMPORTANT OPTIMIZATION!!!
	processedPositionalParameterValues = getPositionalParameterValues();
	processedPositionalParameterTypes = getPositionalParameterTypes();
	processedSQL = sql;
}

where the contains condition prevents parameter binding.
This is the filter definition:
