Exception in thread “commons-pool-EvictionTimer”
刚遇到这个问题，以为是maven运行时内存不足，于是修改maven的运行时内存大小为-Xms512m -Xmx512m -XX:PermSize=512m -XX:MaxPermSize=512m
通过定义MAVEN_OPTS和修改mvn.bat方式都 没成功，又报错

SEVERE: Exception:
java.lang.OutOfMemoryError: PermGen space

通过上网查询java.lang.OutOfMemoryError: PermGen space得知是Java JVM内存溢出导致，于是又在eclipse中
Java->installed JREs->edit->default VM arguments增加了
-Xms512m -Xmx512m -XX:PermSize=512m -XX:MaxPermSize=512m
相当于增加了Java虚拟机的运行时内存，就成功了，不报错了。

网上查的设置环境变量JAVA_OPTS也可以，但是好像要重启eclipse和java jvm，因为我设置后没有及时生效让我误认为不行，后来发现可以，所以就又编辑了博客。
