WAS 5.0.x uses the Interoperable Name Service (INS) protocol
The initial context factory now uses a default provider URL of corbaloc:iiop:localhost:2809.
In previous versions of WAS, the initial context factory used a different ORB implementation, which used legacy protocol. In the legacy ORB, the bootstrap host and port values defaulted to localhost and 900, respectively.
The created subprocess does not have its own terminal or console. All its standard io (i.e. stdin, stdout, stderr) operations will be redirected to the parent process through three streams (Process.getOutputStream(), Process.getInputStream(), Process.getErrorStream()). The parent process uses these streams to feed input to and get output from the subprocess. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock.
