 Interactive test JPasswordFieldTest0006 from
JCK-runtime-api-122/tests/api/javax_swing/interactive/JPasswordFieldTests.java
doesn't repaint JPasswordField component immediately after setting new echo
character. This produces malformed mix of old and new echo characters while
editing JPasswordField component.

===============================================================================
After an evaluation and a smaller sample code, I've determined that this is
a JDK bug and re-assigned it to the JDK Swing team.

The following sample code should display the problem.

1. Change the echoChar let's say to '$'. Be sure to enter a Return.

2. Click the JPasswordField, you'll see a jumble of old echoChar as well
   as some new one.

3. Click the button "Repaint JPasswordField" or resize the frame and
   JPasswordField will display only the new echoChar.

javax.swing.JPasswordField jPF_password = new javax.swing.JPasswordField();

I initialize this JPasswordField component with a default value (e.g.: toto).
If I set the focus on this component, I cannot use arrows (cursor) keys.
I cannot use remove and delete keys too !!!
