Looking at the revised JAR specification, approved in [1], it is
disappointing that the spec contains text which is specific to

context JAR. Any duplicated URLs are omitted.|
That text would seem not to apply to javac and other tools that may wish
to process the class files in a JAR file.
|Agreed it might be good to fix it if possible. All the preceding text
is good, and can be handled by javac. The only questionable bit is the
text "Any duplicated URLs are omitted" which could be moved up a bit in
the spec to a new paragraph, and maybe rephrased to use "ignored"
instead of "omitted". If that were done, all the stuff about class
loaders could be taken as non-normative text.
I've updated the spec changes in the CSR[1] to address your concerns.
For reference, the new relevant passages are:
"Invalid entries are ignored. Valid entries are resolved against the
context JAR.
If the resulting URL is invalid or refers to a resource that cannot be
found,
then it is ignored. Duplicate URLs are ignored.
The resulting URLs are inserted into the class path,
immediately following the URL of the context JAR.
For example, given the following class path:"
Let me know if this will work for javac, and I will proceed.
