     There's nothing (as far as I know) that records the actual use
of a deprecated method.  The compiler will issue a warning if the
method call appears somewhere, but if the user ignores the warning
and runs the code anyhow -- well, then it's just ordinary Java code.
Also, the presence of a method call in source doesn't prove that the
method will actually be called; perhaps your deprecated method is
only called from one of *their* deprecated methods ...

     All I can think of is that you might release a new version of
your library, putting a call to deprecatedMethodWasUsed() at the
start of each deprecated method.  dMWU() could then make some kind
of record of the use, or even "phone home" with the news.  (I am not
a lawyer, but I suggest you consult one before inserting "phone home"
actions; you might easily cross the line into becoming spyware if you
do that sort of thing without the client organization's permission.)
