<p>Hello</p>
<p><br>
</p>
<p>Here is my attempt to fix <a href="https://bugs.openjdk.java.net/browse/JDK-8176571">
https://bugs.openjdk.java.net/browse/JDK-8176571</a>. The same applies to jdk9 and 10.</p>
<p>It changes the NMT category of CHeapBitMap which is used only in G1 code. Given that the class is defined in "share" scope, and it may be used elsewhere in the future, perhaps it should be made made a template? That will add more boilerplate code to g1 sources.</p>
