Code with reflection is ~6% faster on server JRE (in 1.9.0-RC1) and ~1%
slower on client JRE.
So apparently it's not a big deal.
Server JRE:
user> *clojure-version*
{:major 1, :minor 8, :incremental 0, :qualifier nil}
user> (use 'criterium.core)
nil
user> (bench (.length (.toString (reduce (fn [s
Correction - it's not about regex parsing. I removed reflection calls for
StringBuilder and now it seems to be on par in speed.

Hi,
is it expected that code which does a lot of regex parsing is ~14% slower
than it was under Clojure 1.8?

Sorry, my bad. I can see the same behavior in previous Clojure versions
too. I discovered this in the middle of moving to 1.9.0-RC1 in one of
the projects and somehow got it all mixed up.

I see the same behavior in Clojure 1.7.0 and 1.8.0 as you see in 1.9.0-RC1.

Sorry, I did not specify the problem completely earlier. The coercion fails
only when *uncheked-math* is set to truthy in 1.9.0-RC1.
user=> (byte \a)
97
user=> (set! *unchecked-math* true) ; or :warn-on-boxed
true
user=> (byte \a)
ClassCastException java.lang.Character cannot be cast to java.la
Works for me in 1.9.0-RC1. I don't know of anything that changed in this
area.
Clojure 1.9.0-RC1
user=> (byte \a)
97

The coercion (byte \a) works fine in Clojure 1.8, but it fails with
`ClassCastException java.lang.Character cannot be cast to java.lang.Number`
in 1.9.0-RC1. Is this by design?

Hi David,
Clojure 1.9 now depends on two external dependencies (spec.alpha and
core.specs.alpha) so the instructions listed there will no longer work. We
are evaluating whether and how to update those instructions in the readme
right now.
Most Clojure users work with Clojure through a project
I'm getting an error when I follow the instructions in the readme.txt, am I
missing something?
java -cp clojure-1.9.0-RC1.jar clojure.main
Exception in thread "main" java.lang.ExceptionInInitializerError
at java.base/java.lang.Class.forName0(Native Method)
at java.base/java.lang.C
Clojure 1.9 (and 1.8, and every other prior version of Clojure!) works with
Java 9 due to the care that Java takes in retaining backward compatibility.
Clojure 1.0 works just fine with Java 9.
However, there have been some changes that affect various tools, most
prominently Leiningen and Boot.
Is Clojure 1.9 expected to support JDK9? Or is that support reserved for a
later version?

We've switched both of our main projects to RC1 and have had no issues yet.

We have three processes running RC1 in production as of today. Looks good so
far. We’ve had everything else up and running on Beta 4 in production since
Monday, also looking good.

I haven't uncovered any regressions yet on beta4 & have upgraded a few
libraries and apps; though none are in production yet I've been working
with it more or less daily since the beta4 release.
