else already noticed)

Here are my 2 cents:

- the text of the “assembly exception” is specific to the OpenJDK and
derivatives: this code is used widely but there are very few projects
that can use this licensing because of its specificity.

- the “assembly exception” text and the designated modules list refers
to the classpath exception and I do not know of any case of "assembly
exception" texts and designated modules list used without a reference
to the classpath exception so far.

- Wayne suggested to introduce a new "with assembly with classpath"
expression syntax to deal with the “assembly exception” and "classpath
exception" cases.

Instead, the way I am handling this for now to detect licensing
properly in ScanCode is with a new "openjdk-exception" key that has
the combined text of the classpath-exception-2.0 and the "assembly

The benefits are that there is no need to deal with any new "with
with" expression syntax and I think it captures well the cases where
the classpath exception is used alone or used with the assembly
exception (e.g. as "openjdk-exception") and this avoids to create a
special case for this.
