Linux环境下Java运行问题集合

docker容器ubuntu环境下问题

1. 在ubuntu中运行java命令，出现一下问题:

Picked up _JAVA_OPTIONS: -XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap
Unrecognized VM option 'UseCGroupMemoryLimitForHeap'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

终端中配置环境变量

export _JAVA_OPTIONS="-Xms1024m -Xmx1024m

为JVM分配空间，再次运行即可解决问题
