PaperMC believes that 1.16.2 is now ready for general release as we fixed the main issue plagueing the 1.16.x release, the MapLike data conversion issues. Until now, it was not safe for a server to convert a world to 1.16.2 without data conversion issues around villages and potentially other things. If you did, those MapLike errors meant something went wrong. This is now resolved. Big thanks to all those that helped, notably @BillyGalbreath and @Proximyst who did large parts of the update process with me. Please as always, backup your worlds and test before updating to 1.16.2! If you update to 1.16.2, there is no going back to an older build than this. --------------------------------- Co-authored-by: William Blake Galbreath <Blake.Galbreath@GMail.com> Co-authored-by: Mariell Hoversholm <proximyst@proximyst.com> Co-authored-by: krolik-exe <69214078+krolik-exe@users.noreply.github.com> Co-authored-by: BillyGalbreath <BillyGalbreath@users.noreply.github.com> Co-authored-by: stonar96 <minecraft.stonar96@gmail.com> Co-authored-by: Shane Freeder <theboyetronic@gmail.com> Co-authored-by: Jason <jasonpenilla2@me.com> Co-authored-by: kashike <kashike@vq.lc> Co-authored-by: Aurora <21148213+aurorasmiles@users.noreply.github.com> Co-authored-by: KennyTV <kennytv@t-online.de> Co-authored-by: commandblockguy <commandblockguy1@gmail.com> Co-authored-by: DigitalRegent <misterwener@gmail.com> Co-authored-by: ishland <ishlandmc@yeah.net>

Subject: [PATCH] Set cap on JDK per-thread native byte buffer cache
|
|
|
|
See: https://www.evanjones.ca/java-bytebuffer-leak.html
|
|
|
|
This is potentially a source of lots of native memory usage.
|
|
|
|
We are clearly seeing native usage upwards to 1-4GB which doesn't make sense.
|
|
|
|
Region File usage fixed in previous patch should of tecnically only been somewhat
|
|
temporary until GC finally gets it some time later, but between all the various
|
|
plugins doing IO on various threads, this hidden detail of the JDK could be
|
|
keeping long lived large direct buffers in cache.
|
|
|
|
Set system properly at server startup if not set already to help protect from this.
