java.lang.ClassNotFoundException: org.hibernate.validator.method.MethodValidator

Hi,

I have a deployment issue after upgrading my app to spring-cloud Dalston.SR1:

I am using spring boot 1.5.4 which brings in hibernate-validator 5.3 and this one no longer has this class. When i downgrade hibernate-validator to latest 4.x i am getting a different error

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'encryptionBootstrapConfiguration': Unsatisfied dependency expressed through field 'key'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'encrypt-org.springframework.cloud.bootstrap.encrypt.KeyProperties': Initialization of bean failed; nested exception is java.lang.AbstractMethodError: org.hibernate.validator.internal.engine.ConfigurationImpl.getDefaultParameterNameProvider()Ljavax/validation/ParameterNameProvider;

	at org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:88)
	at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues

Not sure how to get out of this, seems that spring 4 requires validator 4.x but spring-cloud needs 5.x , is this correct ?

Apologies if this is not the correct spring-cloud subproject, but since cloud.zookeeper is first in the stacktrace i am posting it here.

I think spring boot 1.5.x requires validator 5.x. Not sure there is much I can do.

Thanks for confirming, after a few attempts i managed to get the right combination of classpath tweaking by forcing weblogic to use both javax.validation and org.hibernate.validator from the application rather than the server (prefer-application-packages for the weblogic initiated)
