How reproducible:
Consistently

Steps to Reproduce:
1. Load an entity that has
    @Lob
    @Column....
    @Basic(fetch = FetchType.LAZY)
2. Clear the session cache
3. Merge the entity

Actual results:
java.lang.ClassCastException: org.hibernate.bytecode.instrumentation.spi.LazyPropertyInitializer$1 cannot be cast to [B

Expected results:
Merge should work
