The LLP client and server components described in these sections are included for legacy backward compatibility only. They are not supported for new application development. If you are developing a new application, use Iguana as the transport mechanism for sending messages over LLP, and use the Iguana plugin API to define an interface between your application and the Iguana server. For more details on using plugins in Iguana, see Working With Plugins. For reasons why you should use Iguana instead of Chameleon for your LLP solution, see Why Choose Iguana Over Chameleon?.

Some customers using Java have used the LLP components with multiple threads. This does not reflect correct usage of the LLP components since they are not designed to work in applications that separate network events onto different threads.

This incorrect usage may not become immediately apparent under some Java virtual machines (JVM) that simulate Java threads virtually rather than running true native operating system threads. When the threads are virtual, the LLP components appear to work correctly. However, when the application is run under a JVM that runs true OS threads for each Java thread, the application will fail.
