Looks like the way to do this is write a custom protocol handler class (extending any of the standard handlers like org.apache.coyote.http11.Http11Protocol) and specifying that class name in the protocol attribute as follows,
<subsystem xmlns="urn:jboss:domain:web:1.2" default-virtual-server="default-host" native="false">
<connector name="https" protocol="com.yourcompany.infra.CustomHttpsHandler" scheme="https" socket-binding="https" enable-lookups="false" secure="true">
<ssl name="ssl"
key-alias="test"
password="nextgen!"
certificate-key-file="/Users/sarul/jboss-as-7.1.3.Final/standalone/configuration/test.keystore"
protocol="TLSv1"
verify-client="false"/>
</connector>
<connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
<virtual-server name="default-host" enable-welcome-root="true">
<alias name="localhost"/>
<alias name="example.com"/>
</virtual-server>
</subsystem>
This seems to work for me so far.
