    RestEasy on 7.1.0CR1 "random" "Bad Arguments/Object is not instance of defining class" failures

      Hi,

       

      We have SLSB as REST resources. Call to the services fail randomly - e.g. may take several server restarts to make error "go away".

       

      The error is:

      org.jboss.resteasy.spi.InternalServerErrorException: Bad arguments passed to public com.vantage.capital.service.wssimple.system.SystemStatusCheck com.vantage.capital.service.wssimple.system.SystemService.systemStatus()  ( )

      .......

      at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) [:1.6.0_21]

       

      Snip of code
      @GET
      @Path("/status")
      @Produces("application/vnd.vantage.capital.system.status+xml")
      public SystemStatusCheck systemStatus() {
      return new SystemStatusCheck("OK");
      }

       

      I'm unable to determine a pattern to the work/fails behaviour - but nothing more than a server restart is needed to make it go away.

       

      Any thoughts?

       

      Thanks

      Michael
