I will revert the change using new bug. Since this is still not marked as resolved, I will use the same bug id to push the new change with bug number.

I forgot to add bug id as part of hg commit log :( http://hg.openjdk.java.net/openjfx/9-dev/rt/rev/653ce34aafba I think we should have some hooks to catch these kinda bugs before pushing it.


"%p" format specifier should be used to print a pointer type, JLObject type(is an C++ non primitve) has been printed in the problematic case which is not allowed. Even though there is a operator overloaded to convert to jobject, which is not implicitly used by GCC family of compilers. Explicit typecasting to jobject converts the JLObject type to jobject which is a type of "typedef _jobject *jobject;". Following error will be thrown without the proposed fix, /Volumes/Works/openjfx-dev/rt/modules/javafx.web/src/main/native/Source/WebCore/bridge/jni/jsc/JavaInstanceJSC.cpp:434:86: error: cannot pass non-trivial object of type 'JLObject' (aka 'JLocalRef<_jobject *>') to variadic function; expected type from format string was 'void *' [-Wnon-pod-varargs] LOG_ERROR("Could not get javaInstance for %p in JavaInstance::defaultValue", jlinstance); ~~ ^~~~~~~~~~ /Volumes/Works/openjfx-dev/rt/modules/javafx.web/src/main/native/Source/WTF/wtf/Assertions.h:341:80: note: expanded from macro 'LOG_ERROR' #define LOG_ERROR(...)

[~arajkumar] Can you add description like why debug build failed only on OSX? and why type casted to jobject..

Looks good to me +1.
