docs: The InTrace UI supports a nice format for specifying multiple classes
  in a single string of text -- convenient for copy-n-paste.
  If you want com.ibm.MyClass and com.hp.YourClass, then delimit the multiple classes with a bar (|), like this:
  com.ibm.MyClass|com.hp.YourClass
  in the "classes" instrumentation dialog (http://mchr3k.github.io/org.intrace/ui.html).
  This syntax also works when requesting classes to be instrumented via code and the server agent.
