A late change to Validator.isChar() see LPS-24601 has broken the service builder when using a namespace that has an "_" character in it.

 <namespace>SCD_TEST</namespace>

The following error is thrown

     [echo] java.lang.RuntimeException: The namespace element must be a valid keyword
     [echo]     at com.liferay.portal.tools.servicebuilder.ServiceBuilder.<init>(ServiceBuilder.java:609)
     [echo]     at com.liferay.portal.tools.servicebuilder.ServiceBuilder.<init>(ServiceBuilder.java:430)

The use of "_" in the namespace within the service builder was prior to this change perfectly valid and was fully tested and working right up to Liferay 6.1 GA 1
