Selecting JPAExpressions.type throws java.lang.ClassCastException

[tox87]

I am trying to fetch entity class by id (single table inheritence), but query:
from(DOCUMENT).select(JPAExpressions.type(DOCUMENT)).where(DOCUMENT.id.eq(id)).fetchOne();
throws java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.String

Debugging AbstractJPAQuery#getSingleResult shows that I get java.lang.Class but fetchOne casts it to string since JPAExpressions.type(DOCUMENT) returns StringExpression.

QueryDSL-JPA 4.1.4

Looks like the root cause can be the same for #1747

If anyone should encounter the same problem:

Expressions.dslTemplate(Class.class, "type({0})", path)

Did it for me. Seems to be a very similar solution to the fix proposed in #1747
