/**
* The Session class represents a mail session and is not subclassed.
* It collects together properties and defaults used by the mail API's.
* A single default session can be shared by multiple applications on the
* desktop. Unshared sessions can also be created.
*
* The Session class provides access to the protocol providers that
* implement the Store, Transport, and related
* classes. The protocol providers are configured using the following files:
*
* -
javamail.providers and
* javamail.default.providers
* -
javamail.address.map and
* javamail.default.address.map
*
*
* Each javamail.X resource file is searched for using
* three methods in the following order:
*
* -
java.home/lib/javamail.X
* -
META-INF/javamail.X
* -
META-INF/javamail.default.X
*
*
* The first method allows the user to include their own version of the
* resource file by placing it in the lib directory where the
* java.home property points. The second method allows an
* application that uses the JavaMail APIs to include their own resource
* files in their application's or jar file's META-INF
* directory. The javamail.default.X default files
* are part of the JavaMail mail.jar file.
*
* File location depends upon how the ClassLoader method
* getResource is implemented. Usually, the
* getResource method searches through CLASSPATH until it
* finds the requested file and then stops.
*
* The ordering of entries in the resource files matters. If multiple
* entries exist, the first entries take precedence over the later
* entries. For example, the first IMAP provider found will be set as the
* default IMAP implementation until explicitly changed by the
* application. The user- or system-supplied resource files augment, they
* do not override, the default files included with the JavaMail APIs.
* This means that all entries in all files loaded will be available.
*
* javamail.providers and
* javamail.default.providers
*
* These resource files specify the stores and transports that are
* available on the system, allowing an application to "discover" what
* store and transport implementations are available. The protocol
* implementations are listed one per line. The file format defines four
* attributes that describe a protocol implementation. Each attribute is
* an "="-separated name-value pair with the name in lowercase. Each
* name-value pair is semi-colon (";") separated. The following names
* are defined.
*
*
*
* Attribute Names in Providers Files
*
*
* Name Description
*
*
* protocol
* Name assigned to protocol.
* For example, smtp for Transport.
*
*
* type
* Valid entries are store and transport.
*
*
* class
* Class name that implements this protocol.
*
*
* vendor
* Optional string identifying the vendor.
*
*
* version
* Optional string identifying the version.
*
*
*
* Here's an example of META-INF/javamail.default.providers
* file contents:
*
* protocol=imap; type=store; class=org.glowroot.shaded.sun.mail.imap.IMAPStore; vendor=Oracle;
* protocol=smtp; type=transport; class=org.glowroot.shaded.sun.mail.smtp.SMTPTransport; vendor=Oracle;
*
*
* javamail.address.map and
* javamail.default.address.map
*
* These resource files map transport address types to the transport
* protocol. The getType method of
* org.glowroot.shaded.javax.mail.Address returns the address type. The
* javamail.address.map file maps the transport type to the
* protocol. The file format is a series of name-value pairs. Each key
* name should correspond to an address type that is currently installed
* on the system; there should also be an entry for each
* org.glowroot.shaded.javax.mail.Address implementation that is present if it is
* to be used. For example, the
* org.glowroot.shaded.javax.mail.internet.InternetAddress method
* getType returns "rfc822". Each referenced protocol should
* be installed on the system. For the case of news, below,
* the client should install a Transport provider supporting the nntp
* protocol.
*
* Here are the typical contents of a javamail.address.map file:
*
* rfc822=smtp
* news=nntp
