NullPointerException when unmarshaling JSON, when quarkus-elytron-security-properties-file is used

When adding the dependency quarkus-elytron-security-properties-file, and setting up security in application.properties, calling a REST endpoint with a JSON body fails to map JSON to a POJO

Steps to reproduce:

Clone latest rest-json

mvn io.quarkus:quarkus-maven-plugin:0.25.0:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=rest-json \
    -DclassName="org.acme.rest.json.FruitResource" \
    -Dpath="/fruits" \
    -Dextensions="resteasy-jackson"

Add to POM

<dependency>
  <groupId>io.quarkus</groupId>
  <artifactId>quarkus-elytron-security-properties-file</artifactId>
</dependency>

Add to application.properties

quarkus.security.users.file.enabled=true
quarkus.security.users.file.users=users.properties
quarkus.security.users.file.roles=roles.properties
quarkus.security.users.file.realm-name=SN
quarkus.security.users.file.plain-text=true

Add files: roles.properties auser=User

users.properties auser=password

Add a simple POJO like: Test.java

package org.acme.rest.json;

import java.util.Objects;

public class Test {
    private String one;
    private Integer two;

    public Test() {
    }

    public Test(String one, Integer two) {
        this.one = one;
        this.two = two;
    }

    public String getOne() {
        return one;
    }

    public void setOne(String one) {
        this.one = one;
    }

    public Integer getTwo() {
        return two;
    }

    public void setTwo(Integer two) {
        this.two = two;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        Test test = (Test) o;
        return Objects.equals(one, test.one) &&
                Objects.equals(two, test.two);
    }

    @Override
    public int hashCode() {
        return Objects.hash(one, two);
    }

    @Override
    public String toString() {
        return "Test{" +
                "one='" + one + '\'' +
                ", two=" + two +
                '}';
    }
}

Change FruitResource to POST, and use POJO as input parameter:

@POST
    @Produces(MediaType.TEXT_PLAIN)
    public String hello(Test t) {
        return t.toString();
    }

I can reproduce the problem both in Quarkus 0.25 and the latest master. I’ll look into it.

@stuartwdouglas I think you’ll probably have to look at this one. I was able to track this down to AuthenticationRequestContext#runBlocking being problematic (see details of what I did to arrive to this conclusion at the end).

It seems like when AuthenticationRequestContext#runBlocking is used, the io.vertx.core.http.impl.HttpServerRequestImpl is read and closed thus causing RESTEasy to not read any data from the request body when it has it’s turn to run.

---

Details pointing to AuthenticationRequestContext#runBlocking as the culprit

Initially I wanted to take all dynamicity out of ElytronPasswordIdentityProvider. So I changed the method body of authenticate to be:

                return context.runBlocking(new Supplier<SecurityIdentity>() {
                    @Override
                    public SecurityIdentity get() {
                        QuarkusSecurityIdentity.Builder builder = QuarkusSecurityIdentity.builder();
                        builder.setPrincipal(new Principal() {
                            @Override
                            public String getName() {
                                return "user";
                            }
                        });
                        builder.addRole("User");
                        builder.addCredential(new Credential() {
                            @Override
                            public String toString() {
                                return "password";
                            }
                        });
                        return builder.build();
                    }
                });

With this change the problem is still present (although it manifests less frequently).

Now if I change the method body to:

        QuarkusSecurityIdentity.Builder builder = QuarkusSecurityIdentity.builder();
        builder.setPrincipal(new Principal() {
            @Override
            public String getName() {
                return "user";
            }
        });
        builder.addRole("User");
        builder.addCredential(new Credential() {
            @Override
            public String toString() {
                return "password";
            }
        });

        CompletableFuture<SecurityIdentity> cf = new CompletableFuture<>();
        cf.complete(builder.build());

        return cf;

the problem goes away completely.
