When I changed the server from Payara 171 to Payara 174, I get the following error on compilation:
Caused by: java.lang.RuntimeException: Uncompilable source code - package javax.validation.constraints does not exist
and all the javax.validation.* imports are marked as does not exist.
My java EE 7 Web application was migrated from glassfish 4.1.1 to Payara 171 without any troubles. I have JDK8 on my work station and my web app is based on JDK7. Any help please
