Too many non-blocking read actions submitted at once.

I got the following exception when I used the Ignore all unmapped target properties action

java.lang.Throwable: Too many non-blocking read actions submitted at once. Please use coalesceBy, BoundedTaskExecutor or another way of limiting the number of concurrently running threads.: 11 with similar stack traces are currently active

使用“Ignore all unmapped target properties”操作重现该问题，然后从堆栈跟踪中的 org.mapstruct.intellij.inspection.UnmappedTargetPropertiesInspection 和 org.mapstruct.intellij.util.MapstructAnnotationUtils 开始。跟踪写操作如何进入 SuggestedRefactoringChangeCollector 及其非阻塞读操作。操作完成且没有出现“Too many non-blocking read actions”异常，即表示完成。
