nit: space after comma

[sgurun-gerrit only, 2013/02/22 01:48:07]

will fix

I think you mean: an async -> a synchronous ?

[sgurun-gerrit only, 2013/02/22 01:48:07]

yeah.

[joth, 2013/02/22 01:15:45]

java_ref_ is a weak ref, so we need to always promote it to a ScopedJavaLocalRef
and check it for null prior to calling obj()

(same pattern as used throughout aw_contents.cc)

[sgurun-gerrit only, 2013/02/22 01:48:07]

Aha... right. But I think I was just looking at the HttpAuthRequest, which is
not doing that!

 ScopedJavaLocalRef<jstring> jrealm = ConvertUTF8ToJavaString(env, realm);
  Java_AwContents_onReceivedHttpAuthRequest(env, java_ref_.get(env).obj(),
                                            handler.obj(), jhost.obj(),
                                            jrealm.obj());
