BUG: SQL Developer 1.5.4 attempting to connect to non-existent local DB.

Question

For some time now I've been seeing SQL Developer 1.5.4 creating a "sqlnet.log" file in "sqldeveloper\sqldeveloper\bin" every time I used it. I've just done some testing and found that it is trying to connect to an XE instance on "localhost" after I close my last open connection. Here are the contents of the "sqlnet.log" file:
Fatal NI connect error 12541, connecting to:
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID=XE)(CID=(PROGRAM=C:\Documents and Settings\ehillma\My Documents\sqldeveloper-154\sqldeveloper\sqldeveloper.exe)(HOST=LMIT-4635)(USER=ehillma))))
VERSION INFORMATION:
     TNS for 32-bit Windows: Version 10.2.0.1.0 - Production
     Windows NT TCP/IP NT Protocol Adapter for 32-bit Windows: Version 10.2.0.1.0 - Production

This is in SQL Developer 1.5.4, Build MAIN-5940, using Java(TM) Platform 1.5.0_17, on Windows XP SP2.

Hi Frank
This message means that the driver code is unable to locate a DLL to load up and use. Looking at the message I suspect that the DLL in question <jtds-dist>\SSO\ntlmauth.dll .
There are a couple of ways of making the Java VM locate the DLL, assuming you are using windows then the easiest would be to add the directory <jtds-dist>\SSO to you path environment (replacing <jtds-dist> with the actual path to your JTDS distribution).
