issue deriving automatic module name

[Paul Bakker]

Hi,

I ran into an issue testing some migration scenarios. When using jboss-transaction-api_1.2_spec-1.0.1.Final.jar as an automatic module, startup fails with:

Caused by: java.lang.IllegalArgumentException: jboss.transaction.api.1.2.spec: Invalid module name: '1' is not a Java identifier

This is clearly a strange JAR name, and can be fixed by providing a module name, but it should probably not prevent startup. 

Best,

Paul
