A DESCRIPTION OF THE PROBLEM :
Technical information:

The problem is related to class javafx.scene.input.Clipboard. The Method getSystemClipboard() contains request for all permissions and does not work without them. It's a bug - code should ask for "accessClipboard".

Unfortunately, SAP code is not involved and we are not able to write workaround in our code to prevent this issue. Oracle's team should fix it inside the JavaFX class.


Source code for related class:
package javafx.scene.input;


...
    /**
     * Gets the current system clipboard, through which data can be stored and
     * retrieved. There is ever only one system clipboard for a JavaFX application.
     * @return The single system clipboard, used for cut / copy / paste operations
     */
    public static Clipboard getSystemClipboard() {
        try {
            final SecurityManager securityManager = System.getSecurityManager();
            if (securityManager != null) {
--> securityManager.checkPermission(new AllPermission());
            }
            return getSystemClipboardImpl();
        } catch (final SecurityException e) {
            return getLocalClipboardImpl();
        }
    }

REGRESSION. Last worked in version 8u51

ADDITIONAL REGRESSION INFORMATION:
Lets check the getSystemClipboard() method in XToolkit class:

    public Clipboard getSystemClipboard() {
        SecurityManager security = System.getSecurityManager();
        if (security != null) {
            security.checkPermission(SecurityConstants.AWT.ACCESS_CLIPBOARD_PERMISSION);
        }
        synchronized (this) {
            if (clipboard == null) {
                clipboard = new XClipboard("System", "CLIPBOARD");
            }
        }
        return clipboard;
    }


***
As You can see XToolkit is checking for
security.checkPermission(SecurityConstants.AWT.ACCESS_CLIPBOARD_PERMISSION);

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Any test application with Swing JFrame + JFXPanel + FX inputField.

Important is initialize SecurityManager without AllPermissions!

try to copy/paste application from
https://javafx-jira.kenai.com/browse/RT-38922

but You need to add your own SecurityManager

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Correction in JavaFX Clipboard class

REPRODUCIBILITY :
This bug can be reproduced always.
