help you fix your problem You should use the @NotNull annotation.
Your boolean is a primitive type, not an object type (Boolean) hence the constraint @NotNull cannot be applied since the primitive type cannot be null. The annotation performs the following validation (formatting added by me):

code :

@NotNull
@Column(name = "DISABLE", nullable = false)
private Boolean disabled;

Hibernate Validator exception "No validator could be found for type: java.lang.String."

hop of those help? You put the @ActorConstraint to the field name which is of type String, while the validator type ActorConstraintValidator is parametrized with Actor. That is, there is no validator for the @ActorConstraint constraint and type String.

Hibernate Validator boolean logic

Hope this helps
I believe one has to create a new annotation to change the default boolean logic behavior. Is this correct?

code :

@ConstraintComposition(OR)
@Pattern(regexp = "[a-z]")
@Size(min = 2, max = 3)
@ReportAsSingleViolation
@Target({ METHOD, FIELD })
@Retention(RUNTIME)
@Constraint(validatedBy = { })
public @interface PatternOrSize {

    String message() default "...";
    Class<?>[] groups() default { };
    Class<? extends Payload>[] payload() default { };

    @OverridesAttribute(constraint=Size.class, name="min")
    int min() default 0;

    @OverridesAttribute(constraint=Size.class, name="max")
    int max() default Integer.MAX_VALUE;

    @OverridesAttribute(constraint=Pattern.class, name="regexp")
    String regexp();
}

Error with validator (No validator could be found for type: java.util.Date.)

I wish this helpful for you As also said in documentation, @NotBlank is for String type. There is no concept of java.util.Date being blank. It can be null or not null.
