GlassFish
On GlassFish, you need to do the following setup to avoid a
java.security.UnrecoverableKeyException with the message Password must not be null:- 1.Edit your domain's
domain.xml(e.g. indomains/domain1/config/domain.xml). - 2.Search for the section of the file that contains
<jvm-options>elements, and there, add:<jvm-options>-Djavax.net.ssl.keyStorePassword=changeit</jvm-options>. If you changed your Glassfish master password, set this property to your new password.
The above steps have been verified on GlassFish 3.1 and 4.1.1.
