纯净版1.12:
jdk8u192(Hotspot懒得更新了又大下载又慢)启动界面490M
jdk8u232-0.17.0(openj9)启动界面350M
还在干活不敢进游戏，所以也没法测fps

最新的mc（1.15.1）已经不支持hotspot虚拟机了，已经联系了mojang。

有没有网盘，我下载也慢的要死.....

不行，无法使用……求教

1.15表示不支持Openj9，另外HMCL需要JavaFX支持，OpenJDK里不带OpenJFX，用HMCL还得先把JavaFX折腾进去。

对GTNH不好使啊...
亲测GTNH 2083, 已发展到IV, FPS降低了40+...
机器是8700K, 16G, GTX 980
内存占用对我来说无所谓, 还是换回之前的java好了...

我发现我以前因为别的版本****装了这个，但是是HotSpot版本
唔又要重搞啊啊啊啊啊啊

最新版OpenJ9，要添加JVM参数-Xjit:disableGuardedStaticFinalFieldFolding
不然会大幅度减帧数，或者启动的时候卡死

这咋办呀，hmcl启动器

内存减少是明显了，但我咋感觉FPS低了不少

我用了openJ9，内存占用和显卡占用降下去了但帧数也下去了...

OSChian的OpenJ9介绍

如果你是HMCL启动器，别安OpenJDK8，安装11，8不带OpenJFX，而且折腾不到，但如果有需要，可以安装双版本
