Initial construction of the typeElementFactory seems to me obsolete. 

var dialectFactory = dialectFactoryF.apply(builder);
this.typeElementFactory = builder.op(invoke(DIALECT_FACTORY_TYPE_ELEMENT_FACTORY, dialectFactory));

src/jdk.incubator.code/share/classes/jdk/incubator/code/internal/OpBuilder.java line 345:

Here we may need to pass the actual type factory, instead of the hard-coded `JavaOp.JAVA_DIALECT_FACTORY`.
