* This class will try to find an unused port and run a JdpTestCase using it. |
|
34 |
* The unused port is needed for jmxremote.port. |
|
35 |
* The problem with busy ports arises when running many automated tests on the same host. |
|
36 |
* Note that jdp.port is a multicast port and thus it can be binded by different processes at the same time. |
