<p class="MsoNormal">Hi, <o:p></o:p></p>
<p>The issue JDK-8291919 you are referring to is caused by “JDK-8279219 <span class="link-summary">
[REDO] C2 crash when allocating array of size too large</span>”. By backing out JDK-8279219, which was done by JDK-8292260, the excess memory consumption is fixed. The excess memory consumption issue was in 11 from 11.0.16 to 11.0.16.1. As you have problems
with 11.0.14.1, you cannot see this bug. <o:p></o:p></p>
<p>Further, “<a href="https://bugs.openjdk.org/browse/JDK-8292301">JDK-8292301</a>
<span class="link-summary">[REDO v2] C2 crash when allocating array of size too large</span>”, which is not backported to 11u as you found out, fixes a crash. So backporting JDK-8292301 will not fix your issue.<o:p></o:p></p>
<p>Best regards, Goetz.<o:p></o:p></p>
