代码报错位置（字符串可以看到json串，但是执行报内存溢出）：

图片说明

我是在本地tomcat8下面跑的，按照网上所说，我修改了catalina.bat文件增大内存，可可是貌似没有生效（如截图所示，本地tomcat数值一直没变），求助

图片说明

catalina.bat 第一行修改了set JAVA_OPTS=-Xms1024m -Xmx1024m -Xss1024K -XX:PermSize=512m -XX:MaxPermSize=2048m，
:noJuliConfig

set "JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%"
JAVA_OPTS='-Xms512m -Xmx1024m'
JAVA_OPTS="$JAVA_OPTS -server -XX:PermSize=512M -XX:MaxPermSize=2048m" 等等，没有用啊。。
分不多，都给你了，真心求教。（纯粹赋值张贴得别拿来了，我也上网搜了还没解决）

求教，在linux上的java多进程，cpu占用超过100%？
