使用JDK 1.6.x G1的经验（“垃圾优先”） [英] Experience with JDK 1.6.x G1 ("Garbage First")

问题描述

我想知道最新的JDK中的G1垃圾回收器有什么经验？我看到> NullPointerException 在我的程序中抛出，尽管代码在先前的JDK中没有改变并且行为正确。

I'd like to know what are the experiences with G1 garbage collector in newest JDK? I see NullPointerException thrown in my program, although code didn't change and behave correctly in earlier JDKs.

推荐答案

我一直在使用jEdit运行：

I've been running jEdit using:

-Xmx192M -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC

最近几天在windows上。没有遇到任何问题或错误行为。

for the last couple of days on windows. Haven't experienced anything going wrong or misbehaving.

我也尝试使用G1 GC来运行Intellij，但这并不公平。它持续了几个小时，然后在一大堆混乱中崩溃，也许有点乐观。

I also tried running Intellij using the G1 GC, it didn't fair so well. It lasted a couple of hours before crashing in a big pile of mess, a bit optimistic maybe.
