I'm still getting the same thing trying to run java/samples/sca/webapp :
java.lang.NullPointerException
java.util.concurrent.ConcurrentHashMap.hash(ConcurrentHashMap.java:157)
java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:730)
org.apache.tuscany.spi.extension.CompositeComponentExtension.getChild(CompositeComponentExtension.java:127)
org.apache.tuscany.core.launcher.CompositeContextImpl.locateService(CompositeContextImpl.java:77)
org.apache.jsp.calc_jsp._jspService(calc_jsp.java:52)
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:332)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.apache.tuscany.runtime.webapp.TuscanyFilter.doFilter(TuscanyFilter.java:57)
I have cleaned the maven repository, did a mvn clean inside java/sca and
java/samples/sca and then a build and still the same.
