java[28013:544956] 22:51:32.241 WARNING: 140: This application, or a library it uses, is using the deprecated Carbon Component Manager

Whenever I open the REPL or play a file, I get an odd Java compiler warning. The full text is

java[28013:544956] 22:51:32.241 WARNING: 140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.

I'm note sure if this is intended for now. What is going on?

I haven't seen anything like this error before.... bizarre.

Could you please post the output of the following commands?

• alda version
• java -version
• boot --version

Doing a quick google, it appears this may be OS X related. What version of OS X are you running? (Or if you're not on OS X, what OS do you use?)

alda v0.12.2

java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)

BOOT_CLOJURE_VERSION=1.7.0
BOOT_VERSION=2.3.0
#App version: 2.2.0

I'm running Mac OS X 10.11. It's not affecting the app's performance or functionality, it's just surprising that it would show up.

Hmm... seems like an El Capitan-related issue. It's come up in a few other places:

jackaudio/jack2#144
cmus/cmus#331
PromyLOPh/pianobar#529

Not sure if there is anything we can do about it in Alda -- seems more low-level than the Java/Clojure libraries we are using.

It's a relief that it's not affecting performance or functionality, at least!
