Fix "Illegal Reflection" warning for Clojure 1.10 & Java 11

[cloojure]

Upgrading from Clojure 1.9 to 1.10, I am getting a new warning:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by clojure.lang.InjectedInvoker/0x0000000800231c40 (file:/home/alan/.m2/repository/org/clojure/clojure/1.10.0/clojure-1.10.0.jar) to method com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl.parse(org.xml.sax.InputSource,org.xml.sax.HandlerBase)
WARNING: Please consider reporting this to the maintainers of clojure.lang.InjectedInvoker/0x0000000800231c40
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

Using Java 11 on Ubuntu 16.04.

This can be fixed by type hints on the net.cgrand.xml/startparse-sax method. I also upgraded the project.clj to current versions of lein and jsoup. Tests are clean:

~/gh/enlive > lein clean ; lein test

lein test net.cgrand.enlive-html.test

lein test tst.net.cgrand.xml

Ran 31 tests containing 105 assertions.
0 failures, 0 errors.

~/gh/enlive > java --version ; lein --version
java 11 2018-09-25
Java(TM) SE Runtime Environment 18.9 (build 11+28)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11+28, mixed mode)

Leiningen 2.9.0 on Java 11 Java HotSpot(TM) 64-Bit Server VM

Uh oh, does the 1st argument have to be nailed down? The docstring (of a function that calls this one in the same file) says s may be "a File, InputStream or String naming a URI". That docstring matches clojure.xml/parse, and both of those functions actually also accept InputSource (which was suggested to be documented in Clojure here (https://dev.clojure.org/jira/browse/CLJ-1290)), which in turn accepts a Reader, which is the most direct way to parse XML content of a string... a StringReader in an InputSource. In short, the new constraint to just accept nothing but InputStream should be documented or, better yet, an alternative found without such a constraint.

This error was resolved by updating from clojure version from 1.10 to 1.10.1 for me.
