I had this issue with a deploy of a spring boot application on weblogic 12c server. The problem is that when I try to deploy this application on my local weblogic server it works fine, but when I deploy the same application (EAR) on pre-prod server, it doesn't.
The weblogic error is: java.io.IOException weblogic.utils.compiler.ToolFailureException
The problem was the version of weblogic server(12.1.3), it doesn't support spring boot 2.2.4. For fix this issue the solution was downgrade my spring boot application to 2.0.4 version.
