> Can someone take a stab at summarizing this for CHANGES.txt, thus avoiding details a reader is unlikely to know about? Like me :-). How will a user of Lucene benefit? ``` * GITHUB#13570, GITHUB#13574, GITHUB#13535: Avoid performance degradation with closing shared Arenas. Index files are mmapped one-to-one with the JDK's foreign shared Arena. The JVM deoptimizes the top few frames of all threads when closing a shared Arena (see JDK-8335480). We mitigate this situation by 1) using a confined Arena where appropriate, and 2) grouping files from the same segment to a single shared Arena. ``` -- This is an automated message from the Apache Git Service.
