Call to LispReader$StringReader breaks with feature expressions patch

[MichaelBlume]

This may be a premature issue, but I thought a heads-up might be useful; the feature expressions patch under discussion for inclusion in Clojure 1.7.0 changes the arity of LispReader$StringReader objects when they are called as functions, causing instaparse's safe-read-string to crash. I reported this on the clojure development board and the response was basically that this was deep enough in Clojure internals that it should be expected to break.

Thanks for the heads up. Fortunately, it sounds like if it's just an arity change, it will be easy to fix when the time comes.

Update: This is in 1.7.0-alpha6

@MichaelBlume
Thanks for the update.

@Engelberg
We'd love to see this issue resolved soon! We use Instaparse through Compojure and our builds are breaking with Clojure 1.7.0-alpha6. Thanks for your hard work!

+1

[seancorfield]

Yes, another +1 here -- this just broke our build since we routinely test against Clojure master (which now includes the changes from Alpha 6).

[seancorfield]

Confirmed this works with Clojure master now for our unit tests. Thank you! Next step is to upgrade our whole stack to Clojure 1.7.0-alpha6 and run a full stack test.
