[Solved] JAVA fx Error: java.lang.instrument ASSERTION FAILED ***: “!errorOutstanding“ with message transform

java fx error: java.lang.instrument ASSERTION FAILED ***: “!errorOutstanding“ with message transform

Problem description

Errors encountered in Java FX

In fxml, the controller is bound by fx:controller.
FXMLLoader.load is used in the controller of control to get the fxml file

An error is reported

java.lang.instrument ASSERTION FAILED ***: "!errorOutstanding" with message transform method call failed at JPLISAgent

Cause analysis:

The reason for the error is that there is a cycle, similar to the cycle dependency problem

as a result of:

a.fxml depends on the controller AController.java
But AController.java will load this fxml again

Solution:

Remove FXMLLoader.load from the controller or remove fx:controller from fxml

Change the port number to another number at this position. Make it larger. Here I change it to 1001

OK, it’s normal
