(Right?). There are plenty of folks here who might be able to answer this question, but I think this is actually off-topic for this list. (No problem; carry on.

I don't believe your JNDI DataSource has anything to do with making outgoing connections to OAuth providers... - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlb0Qx0ACgkQ9CaO5/Lv0PA7KACfYVLubbNfIxKrInh9SNwY/JHf h+kAnRRevkPjZBdCl0RD53QdtsndtXGe =h3bQ -----END PGP SIGNATURE----- Thanks for the replay. Yes - that does look like a spring connect timeout - which then passes back to java.net.SocketException: Connection reset. So either the client or the server is resetting before the connection can complete. The only system change to coincide with these connection resets is the new connection pool config as listed above. This implies that there is some conflict within the datasource config.
