> Project: HBase
> Issue Type: Improvement
> Components: UI
> Reporter: Xiao Liu

> Priority: Minor
> Labels: pull-request-available

>
> On the process info pages ({{processMaster.jsp}} and {{processRS.jsp}}), the
> memory pool loop skips code cache pools via:
> {code:java}
> if (mp.getName().contains("Cache")) continue;
> {code}
> This only matches the JDK 8 pool name "Code Cache". Since JDK 9 (JEP 197:
> Segmented Code Cache), the code cache is split into three pools named
> {{CodeHeap 'non-nmethods'}}, {{CodeHeap 'profiled nmethods'}} and
> {{CodeHeap 'non-profiled nmethods'}}. None of them contain "Cache", so on
> JDK 9+ (including 11/17/21) these three pools are no longer skipped and show
> up on the page, which was not intended.
> *Fix:* also skip pools whose name contains "CodeHeap", keeping the existing
> "Cache" check for JDK 8 compatibility. Applied to both {{processMaster.jsp}}
> and {{processRS.jsp}}.
> The unrelated "Commited" -> "Committed" header typo on the same tables is
> fixed together.
