When does the Netprobe connect to the JMX enabled Java application

It connects on the plugin's first sample. Once the connection is established, the Netprobe reuses the connection for succeeding samples.

For example:

• You have 3 JMX samplers.
• Sampler 01 is connecting to Java app A.
• Sampler 02 is connecting to Java app A.
• Sampler 03 is connecting to Java app B.

The effect of this is that the Netprobe will create only 2 connections:

• 1 connection to Java app A, and
• 1 connection to Java app B.

The Netprobe will also keep the connection open. Sampler 01 and Sampler 02 will share 1 connection to Java app A.
