Not sure this is the correct list. Please redirect as appropriate.
I believe core-libs is the appropriate place. Cc:d.
Please review the following proposed change:
There are 3 asserts in unpack.cpp which check only constants, and which the compiler rejects as 'has no effect' (in fastdebug builds). This seems to be caused by:
https://bugs.openjdk.java.net/browse/JDK-8211029
I propose to fix this by defining a STATIC_ASSERT which can evaluate and reject this at compile time:
Webrev: http://cr.openjdk.java.net/~rkennke/JDK-8211071/webrev.00/
From a build perspective, this looks good. But please let someone from core-libs review also.
Bug: https://bugs.openjdk.java.net/browse/JDK-8211071
It might be useful to define the STATIC_ASSERT in a more central place to be used elsewhere too. For example, there is a similar #define in Hotspot's debug.hpp
Unfortunately, we do not have a good place to share definitions like this across JDK libraries. :-( The need for that has struck me more than once. For some stuff, we mis-use jni.h. But it would definitely be out of line to add a STATIC_ASSERT there. /Magnus
Thanks, Roman
