RFR: 8266567: Fix javadoc tag references in sun.management.jmxremote.ConnectorBootstrap

[Pavel Rappo]

This fixes two javadoc tag references and several typos. References are fixed by removing whitespace before the opening `(`. That whitespace caused the opening `(` and the rest of the reference to be parsed as a link label.

Since we are here, I think this class could also benefit from using modern APIs. This should be done in a separate PR though. For example:

1. Numerous instances of `Boolean.valueOf( <var> ).booleanValue()` could be changed to `Boolean.parseBoolean( <var> )`
2. `throw (IllegalArgumentException) new IllegalArgumentException(msg).initCause(e);` could be changed to `throw new IllegalArgumentException(msg, e);`
