I'm not 100% sure what you mean by "reserved" but I will guess that
you asking if there is a complete list of the system properties
defined by the Java SE APIs and perhaps the list of JDK-specific
system properties too. Off-hand, I'm not aware of a master list, they
are instead "buried" in the API specs. Is the context the system
properties that JAXP 1.5 is proposing to define?
Yes, those defined by the Java SE APIs or the JDK-specific system
properties. Not related to JAXP 1.5, I'm just asking a general question
to find out if there's an API to get the 'master' list.
As with Alan I don't know what you mean by "reserved". The
documentation you link to above tells you what properties must exist.
But an implementation can add other properties. I don't know if there
is any rule that says they can't add properties in the java.* namespace.
I meant to ask if there's an API to get the list of JDK-specific system
properties, and it seems there's none.
