[ https://issues.jboss.org/browse/WFLY-10752?page=com.atlassian.jira.plugin... ] d3coder d3coder updated WFLY-10752: ----------------------------------- Description: I'm making simple app. In one of my DTO's i have field with `javax.validation.constraints.Email` annotation. When this annotation present, wildfly fails to deploy my app with this exception: https://gist.github.com/XakepSDK/daa2531203b365ad1969e01b4466b8a1 My DTO class: https://gist.github.com/XakepSDK/a78245b262315437d2800be524018d2e CrossField annotation: https://gist.github.com/XakepSDK/fde1553339c18bc442820868f573a53a CrossField validator: https://gist.github.com/XakepSDK/391783e3b79f839a93a8f45c886b38e0 java -version openjdk version "1.8.0_172" OpenJDK Runtime Environment (build 1.8.0_172-b11) OpenJDK 64-Bit Server VM (build 25.172-b11, mixed mode) <------------------ UPD: ------------------> I got it, this happens if @Size present with @Email. Simple test class: https://gist.github.com/XakepSDK/892ec3d886ec2cac7f44d93faa0868c1 UPD: this happens if field annotated with Email and any other validation annotation. It failed with Email and NotNull. UPD: Maven project and WAR with [^bvbug-1.0-SNAPSHOT.war] minimal repro. code Actually, this project doesn't show issue like my first app, but Email validation doesn't work too. Make a POST request to `/` with this: `{"email":"test"}` or {"email":"test@test.test"}`. Content-Type: application/json. You will get `NullPointerException` in response, without any extended message.(i made special mapper for that, but seems it doesn't work) In another project, wilfdly refuses to start with NullPointerException, here it work only for request. I don't know, how to make it work like in another project. was: I'm making simple app. In one of my DTO's i have field with `javax.validation.constraints.Email` annotation.
