jdbc, pgsql6.5.1, large objects

Hey folks,

Let's see, my admin just upgraded postgresql to 6.5.1 and now it looks
like FastPath isn't working. More specifically, after creating and opening
a large object using the LargeObjectManager class, any other access
attempts throws the following:

FastPath call returned ERROR: lo_write: invalid large obj descriptor (0)
FastPath call returned ERROR: lo_write: invalid large obj descriptor (0)
at postgresql.fastpath.Fastpath.fastpath(Fastpath.java:141)
at postgresql.fastpath.Fastpath.fastpath(Fastpath.java:188)
at postgresql.largeobject.LargeObject.write(LargeObject.java:173)
at postgresql.largeobject.LargeObject.write(LargeObject.java:188)
at uploadImage.main(uploadImage.java:87)

In this case, line 87 in uploadImage is:
...
85 LargeObject pict = lobjm.open(num);
86 while ((s=fblob.read(buf, 0, 256)) > 0) {
87 pict.write(buf, 0, s);}
...

Before upgrading to 6.5.1, this program worked fine. Calls to tell, size,
read all cause the same type of exceptions.

Any help would be appreciated.

Other info: FreeBSD 3.2, jdk1.1.8
