POP3Store fails to authenticate, only in Tomcat7 (works fine in unit tests)
This the code, which works perfect in a unit test (connects to Gmail):

    Properties props = new Properties();
    props.put("mail.pop3.ssl.enable", true);
    props.put("mail.pop3.host", "pop.gmail.com");
    props.put("mail.pop3.port", "995");
    javax.mail.Session.getDefaultInstance(props, null)
      .getStore("pop3")
      .connect("foo@...", "password");

When I run the same code in Tomcat7:

    ...
    Caused by: javax.mail.AuthenticationFailedException: failed to connect
      at javax.mail.Service.connect(Service.java:332)
      at javax.mail.Service.connect(Service.java:176)
      at javax.mail.Service.connect(Service.java:196)

What is it about?

Well, I already configured `META-INF/javamail.providers`:

    protocol=pop3; type=store; class=com.sun.mail.pop3.POP3Store;

And I have these Maven dependencies in `WEB-INF/lib`: `javax.mail:mail:1.4.4` and `com.sun.mail:pop3:1.4.4`.
