Hello,

When I start the project, everything will go well.

The problem occurs when I run debug mode. It goes through all the "Line Breakpoints". After the last, the project starts, but it also displays an error.
{code:java}
java.lang.NullPointerException at org.netbeans.modules.debugger.jpda.jdi.ReferenceTypeWrapper.fieldByName(ReferenceTypeWrapper.java:1033) [catch] at org.netbeans.modules.debugger.jpda.visual.VisualDebuggerListener.setFxDebug(VisualDebuggerListener.java:463) at org.netbeans.modules.debugger.jpda.visual.VisualDebuggerListener.initDebuggerRemoteService(VisualDebuggerListener.java:273) at org.netbeans.modules.debugger.jpda.visual.VisualDebuggerListener.access$100(VisualDebuggerListener.java:94) at org.netbeans.modules.debugger.jpda.visual.VisualDebuggerListener$3.breakpointReached(VisualDebuggerListener.java:184) at org.netbeans.api.debugger.jpda.JPDABreakpoint.fireJPDABreakpointChange(JPDABreakpoint.java:275) at org.netbeans.api.debugger.jpda.JPDADebugger.fireBreakpointEvent(JPDADebugger.java:466) at org.netbeans.modules.debugger.jpda.JPDADebuggerImpl.fireBreakpointEvent(JPDADebuggerImpl.java:641) at org.netbeans.modules.debugger.jpda.breakpoints.BreakpointImpl.perform(BreakpointImpl.java:535) at org.netbeans.modules.debugger.jpda.breakpoints.MethodBreakpointImpl.exec(MethodBreakpointImpl.java:253) at org.netbeans.modules.debugger.jpda.util.Operator.processEvents(Operator.java:500) at org.netbeans.modules.debugger.jpda.util.Operator.access$800(Operator.java:94) at org.netbeans.modules.debugger.jpda.util.Operator$1.run(Operator.java:225) at org.netbeans.modules.openide.util.GlobalLookup.execute(GlobalLookup.java:45) at org.openide.util.lookup.Lookups.executeWith(Lookups.java:278) at org.netbeans.modules.debugger.jpda.util.Operator$2.run(Operator.java:257) at java.base/java.lang.Thread.run(Thread.java:835)
