-Xms1024m

-Xmx2048m

-XX:ReservedCodeCacheSize=1024m

-XX:+UseConcMarkSweepGC

-Dfile.encoding=UTF-8

-XX:+UseConcMarkSweepGC

-XX:SoftRefLRUPolicyMSPerMB=50

-ea

-Dsun.io.useCanonCaches=false

-Djava.net.preferIPv4Stack=true

-XX:+HeapDumpOnOutOfMemoryError

-XX:-OmitStackTraceInFastThrow

-Xverify:none

-XX:ErrorFile=$USER_HOME/java_error_in_idea_%p.log

-XX:HeapDumpPath=$USER_HOME/java_error_in_idea.hprof

重启idea
