We've just upgraded our Worklight server to 6.0.0.20140208-1639, and we're now frequently getting in the Websphere standard out log the error:
DeployService W com.worklight.integration.services.impl.DeployServiceImpl syncAdaptersFromDB FWLSE0082W: Failed to deploy adapter. This may be due to a JavaScript error in your adapter implementation (archive: 'C:\Windows\TEMP\HelloWorld6506022860570731839.adapter'). [project worklightEMS]
com.worklight.gadgets.bean.InvalidDeployableException: The 'adapter' version 'null' is different than the version of Worklight Server '6.0.0'.
Use Worklight Studio '6.0.0' to build and deploy the application.

There is no "HelloWorld" adapter in c:\Windows\TEMP and we can't find any reference to this in the WL project that was deployed to the server. We rebuilt the WAR and deployed to the server using the same patch release.
Any idea why this error is being triggered and what we can do to stop it?
