FULL PRODUCT VERSION :
JDK 16

ADDITIONAL OS VERSION INFORMATION :
MS Windows 10 OS

A DESCRIPTION OF THE PROBLEM :
Minimizing a dialog window, which is instance for example of "javax.swing.JDialog" class, in a Java application from a second non-Java application by calling Win32 API function "::ShowWindow(hwnd, SW_MINIMIZE)", where "hwnd" argument is HWND of the peer window of the Java dialog window, leads to a postponed JVM crash in "AwtFrame::WmSize" C++ method.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Download and unpack the attached archive "CrashOnMinimizingDialogTest.zip" with the created test case. Go to the directory of the unpacked test case.
2. <JDK_HOME>\bin\javac CrashOnMinimizingDialogTest.java
3. <JDK_HOME>\bin\java CrashOnMinimizingDialogTest
