Unrecognized VM option 'PrintGCDateStamps' Error: Could not create the Java Virtual Machine

这是我在启动mqbroker时报的错误信息

解决方案：

1.vim runbroker.sh打开配置到底部对下面几行无用的进行注释

JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
#JAVA_OPT="${JAVA_OPT} -XX:+UseG1GC -XX:G1HeapRegionSize=16m -XX:G1ReservePercent=25 -XX:InitiatingHeapOccupancyPercent=30 -XX:SoftRefLRUPolicyMSPerMB=0"
#JAVA_OPT="${JAVA_OPT} -verbose:gc -Xloggc:${GC_LOG_DIR}/rmq_broker_gc_%p_%t.log -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCApplicationStoppedTime -XX:+PrintAdaptiveSizePolicy"
#JAVA_OPT="${JAVA_OPT} -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=30m"
JAVA_OPT="${JAVA_OPT} -XX:-OmitStackTraceInFastThrow"
JAVA_OPT="${JAVA_OPT} -XX:+AlwaysPreTouch"
#JAVA_OPT="${JAVA_OPT} -XX:MaxDirectMemorySize=15g"
JAVA_OPT="${JAVA_OPT} -XX:-UseLargePages -XX:-UseBiasedLocking"
JAVA_OPT="${JAVA_OPT} #
-Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext:${BASE_DIR}/lib:${JAVA_HOME}/lib/ext"
#JAVA_OPT="${JAVA_OPT} -Xdebug -Xrunjdwp:transport=dt_socket,address=9555,server=y,suspend=n"

2.正常退出此时在启动依旧报错，但不是Unrecognized VM option 'PrintGCDateStamps' Error错误了此时异常信息依旧是Could not create the Java Virtual Machine
