Keystore password in security realm keystore definition does not support expression

The keystore password in the security realm keystore definition does not support expressions. As a result the password cannot be masked.
This in contrast to the key password, which does support expressions.

Relevant code fragment from org.jboss.as.domain.management.security.KeystoreAttributes :

public static final SimpleAttributeDefinition KEY_PASSWORD = new SimpleAttributeDefinitionBuilder(
ModelDescriptionConstants.KEY_PASSWORD, ModelType.STRING, true).setXmlName(ModelDescriptionConstants.KEY_PASSWORD)
.setValidator(new StringLengthValidator(1, Integer.MAX_VALUE, true, true)).setAllowExpression(true)
.setFlags(AttributeAccess.Flag.RESTART_RESOURCE_SERVICES).build();

public static final SimpleAttributeDefinition KEYSTORE_PASSWORD = new SimpleAttributeDefinitionBuilder(ModelDescriptionConstants.KEYSTORE_PASSWORD, ModelType.STRING, false)
.setXmlName(ModelDescriptionConstants.KEYSTORE_PASSWORD).setValidator(new StringLengthValidator(1, Integer.MAX_VALUE, false, false))
.setFlags(AttributeAccess.Flag.RESTART_RESOURCE_SERVICES).build();
