我有一个正常工作的Grails 3应用程序，该应用程序通常以grails run-app启动。当我尝试从IDE中使用Application.groovy启动它时，我从GORM（下面的stacktrace）中得到了NullPointerException。
我的启动配置不正确吗？为什么行为不同？
这是IntelliJ生成的run-app命令，该命令有效：
"C:\Program Files\Java\jdk1e8.0_211\bin\java.exe" -XX:+TieredCompilation -XX:TieredStopAtLevel=1 -XX:CICompilerCount=3 -Dlogback.rootLogLevel=DEBUG -Djline.WindowsTerminal.directConsole=false -Dgrails.full.stacktrace=true -Dfile.encoding=UTF-8 -classpath C:\Users\rmorrise\AppData\Local\Temp\classpath634969171.jar org.grails.cli.GrailsCli run-app --plain-output
这是Application.groovy的调试命令，该命令不起作用：
"C:\Program Files\Java\jdk1.8.0_211\bin\java.exe" -agentlib:jdwp=transport=dt_socket,address=127.0.0.1:50806,suspend=y,server=n -Dlogback.rootLogLevel=DEBUG -XX:TieredStopAtLevel=1 -noverify -Dspring.output.ansi.enabled=always -Dcom.sun.management.jmxremote -Dspring.jmx.enabled=true -Dspring.liveBeansView.mbeanDomain -Dspring.application.admin.enabled=true -javaagent:C:\Users\rmorrise\.IntelliJIdea2019.1\system\groovyHotSwap\gragent.jar -javaagent:C:\Users\rmorrise\.IntelliJIdea2019.1\system\captureAgent\debugger-agent.jar -Dfile.encoding=UTF-8 -classpath C:\Users\rmorrise\AppData\Local\Temp\classpath1916879940.jar elect.api.Application
我使用Application.groovy启动的原因是可以使用YourKit Profiler代理启动。即使我不使用YourKit代理启动而只是使用“调试”命令，也会发生错误。
我正在使用的应用具有使用discriminator映射的超级/子域类。子映射未能初始化，因为gorm @Entity批注在子代初始化时未应用于父实体。
堆栈跟踪如下：

尝试的解决方法
我试图通过将以下JVM arg添加到运行应用程序启动配置中来附加YourKit分析器：
-agentpath:"C:\Program Files\YourKit Java Profiler 2019.8-b81\bin\win64\yjpagent.dll"
似乎没有将探查器应用于Grails JVM，因为启动CPU性能分析时我仍然遇到挂断。
