jdbc 8 blob not implemented?

 Hi,

 I downloaded the pgjdbc 8.0 driver, and when i tried using the
 getBlob() on a result set, it throws a NotImplemented Exception

 I looked at the code, and it looks like none of the functionality has
 been implemented. Is this a server limitation or such thing, or is it
 work that just needs to be done?

 The real problem is that i can't use the LargeObject API for Blob's,
only bytea. I understand that i can use a getBinaryStream on a result
set, but i want to know what the problem with getBlob is

 Thanks in advance
