Subject NPE when upgrade cxf-codegen-plugin from 2.3.5 to 2.7.4
Date Thu, 16 May 2013 00:45:54 GMT
My Maven build runs wsdl2java by loading a wsdl from the maven repository.
Using cxf-codegen-plugin 2.3.5 works (even 2.7.0 works). But 2.7.4 (in fact,
starts with 2.7.1) give me NPE. I downloaded the latest
apache-cxf-2.7.4-src. The stack trace seemed indicating a
System.getProperty("java.class.path") is not set. Is there any new settings
that is needed starting 2.7.1? Thank you for your help!
