jetty 9.2 + java.lang.OutOfMemoryError: PermGen space 解决办法

我这边的异常发生情况是生产环境   环境是 jetty 9.2   jdk7，

百度了很久没找到解决办法，搜到的倒是不少，不过都没什么鸟用，在Google翻到了，搬运一下。

In Jetty 9.2+

In your ${jetty.base} directory, add the jvm module + default configuration

[user]$ cd mybase
[mybase]$ java -jar /path/to/jetty-distribution/start.jar --add-to-start=jvm
INFO: jvm             initialised in ${jetty.base}/start.ini (appended)
[mybase]$ 
Now go edit your ${jetty.base}/start.ini and configure the properties, uncomment those things that you want (don't forge to uncomment --exec) jetty to use when starting itself up.

Example:

# --------------------------------------- 
# Module: jvm
--module=jvm
## JVM Configuration
## If JVM args are include in an ini file then --exec is needed
## to start a new JVM from start.jar with the extra args.
##
## If you wish to avoid an extra JVM running, place JVM args
## on the normal command line and do not use --exec
--exec
