错误原因是以前低版本idea使用了 JetbrainsCrack类的破解jar包，在安装的新版本idea时，继承了旧版本的idea配置，导致上述错误。

解决方法：

在 C:\Users\hi\.IntelliJIdea2019.2\config下(.IntelliJIdea2019.2---新版本idea)：修改.config文件（idea.exe.vmoptions或者idea64.exe.vmoptions）

# custom IntelliJ IDEA VM options

-Xms128m
-Xmx1463m
-XX:ReservedCodeCacheSize=240m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
//-javaagent:E:\idea\idea\bin\JetbrainsCrack-3.1-release-enc.jar----删除继承的旧版本jar路径
-javaagent:E:\idea\IntelliJ IDEA 2019.2\bin\jetbrains-agent.jar----添加新的

重启。
