Yes, you are right. "test_spaceManager.cpp" should not have been included here. 

Please find the updated webrev at http://cr.openjdk.java.net/~mchinnathamb/8170395/webrev.01/  .

 

Regards,

Muthusamy C

Hi Muthusamy,

Looks okay. But are there gtests already in jdk8u? I thought gtests came with jdk9? 

http://openjdk.java.net/jeps/281

If not, how does http://cr.openjdk.java.net/~mchinnathamb/8170395/webrev.00/test/native/memory/test_spaceManager.cpp.html run or even compile?

Thanks, Thomas

Hi Thomas,

 

>  the webrev link seems to be dead.

Sorry for the trouble.

Please find the corrected link below

http://cr.openjdk.java.net/~mchinnathamb/8170395/webrev.00/

 

Somehow the line following the link got appended to the previous one leading to a dead link.

Hi,

Please review the backport of bug: "JDK-8170395: Metaspace initialization queries the wrong chunk freelist" to jdk8u-dev

Please note that this is not a clean backport due to new entries in debug.cpp and copyright changes.
