java - Is there an alternative to JPasswordField?

Question

When typing a passphrase like

yeast bulk seize is shows pain

everybody can hear tapping the space bar, so it seems logical to display the spaces in the password field, too. So I'd like something capable of showing

***** **** ***** ** ***** ****

instead of

******************************

This would make typing easier while hardly decreasing the security.

UPDATE

Think twice before you update Riduidel's comment. When Bruce Schneier writes "It's time to show most passwords in clear text", then showing a small part of it must be correct, too. Especially showing a part which may get captured simply by listening.

Was thinking JPasswordField was simply a JTextField simply overriding the renderer component, but it seems not to be the case.

So, instead of changing the renderer (like it would be the case if JTextField had such a component), you'll have to use a JTextField with a custom Document holding two strings :

1. Password text as written by user
2. Displayed password

You'll have to make sure all Document modifying methods change the password text, while all rendering methods use the displayed one.
