You can try upgrading to keyring-2.0-pre4.  I'm using it for some time
without problems.  It's upgrade procedure is more careful when reading
records, so it may be better in recovering the records.
Unfortunately there is no way back to keyring-1.2.3 then.

There are already some working java programs on the conduits page.

Alternatively, you can check out keyring-link from the cvs repository, see:
https://sourceforge.net/cvs/?group_id=3D306

The modulename is keyring-link
The directory contains the C-code but there is a java directory with some=20
code to read and decrypt the pdb files.  The java code uses JCE
(Java Cryptographic Environment).  You need to write your own code to
open the database and extracts its contents though.

Use it like this:

  KeyringLibrary library =3D new net.sf.gnukeyring.decoder.PDBKeyringLibrar=
y();
  library.setFilename(new File("Keys-Gtkr.pdb"));
  library.unlock("<secret>");
  Iterator i =3D libraries.getEntries().iterator();
  while (i.hasNext()) {
     KeyringEntry entry =3D (KeyringEntry) i.next();
     System.err.println(entry.getName());
     System.out.println(entry.getField("Account"));
     System.out.println(entry.getField("Password"));
     System.out.println(entry.getField("Notes"));
     System.out.println(entry.getField("Changed"));
  }
