Kim suggested that you should involve the Runtime team:<br>
<pre wrap="">"I'm not sure of this, but I think metaspace belongs to runtime rather
than gc. If so, this should go through the hs-rt repository and have
runtime folks involved in the review."</pre>
not that you should create a new, separate thread on the hotspot-rt
list.<br>

</span> I agree. This is a nice cleanup,
irrespective of any potential performance
gains.<br>

No need to NULL check CHeapObj
allocations, since the JVM will exit if it
failed to get memory. See AllocateHeap:<br>
if (p == NULL && alloc_failmode
== AllocFailStrategy::EXIT_OOM) {<br>
vm_exit_out_of_memory(size,
OOM_MALLOC_ERROR, "AllocateHeap");<br>
}<br>

<div>That part is taken care of on webrev.02. </div>
<div>The conversation is also happening at

Please don't split up a review request that way in the
future. It would have been enough to CC the
hotspot-runtime-dev list.<br>
<br>
I'll leave the rest of my comments on that list.<br>
<br>
Thanks,<br>
