Intellij Idea15 CE无法使用-XX:+ UseG1GC启动 [英] Intellij Idea15 CE fails to launch with -XX:+UseG1GC

问题描述

我正在尝试使用字符串实习来测试运行情况，以查看它是否有助于缓解intellij的大量内存需求.为了使用Java 8的内置实习，您需要运行G1GC.但是，将此参数添加到用户idea.vmoptions文件中会导致jvm无法启动.绝对仅此参数，其他收集器似乎不是问题.捆绑的jre是8u40，我正在OS X上运行.

I am trying to test running with string interning to see if it helps ease the massive memory requirements of intellij. In order to use java 8's built in interning you need to run the G1GC. However adding this parameter to the user idea.vmoptions file causes the jvm to fail to start. It is definitely this parameter only and other collectors seem not to be an issue. The bundled jre is 8u40 and i'm running on OS X.

我还感到奇怪的是，该应用程序是作为平台本机二进制文件启动的，该二进制文件通过jni创建了jvm，但这可能不合时宜.

I also find it odd that the application is launched as a platform native binary which creates a jvm via jni, but that may be beside the point.

推荐答案

使用此配置:

-XX:-UseParallelGC
-XX:-UseConcMarkSweepGC
-XX:+UseG1GC
