Message Title

I get the same error with Hibernate 4.2.3.Final even with the default value of updatable which is true. When I try to merge a detached Entity back into the persistence context and that Entity uses FetchType.LAZY on a byte[] field:

    @Basic (fetch = FetchType.LAZY)
    @Column (name = "LAZY_DATA", columnDefinition = "VARBINARY")
    private byte[] lazyData;

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