/**
* Default implementation of CommandParser which expects the following command format:
*
* [node-type=node-name (, node-type=node-name)*] : operation-name ['(' name=value (, name=value)* ')' ]
*
* the whitespaces are insignificant. E.g.
*
* profile=production,subsystem=threads,bounded-queue-thread-pool=pool1:write-core-threads(count=0, per-cpu=20)
*
* Each node-type, node-name, operation-name and the argument name as strings are checked to be valid identifiers,
* i.e. the Character.isJavaIdentifierStart(c) should return true for the first character and the rest should
* satisfy (Character.isJavaIdentifierPart(c) || c == '-')
*
* This implementation is thread-safe. The same instance of this class can be re-used multiple times and
* can be accessed from multiple threads concurrently w/o synchronization.
