Is Websphere 8.5.5 compatible with Spring 5? The Validation API referenced in spring5 (validation-api 5) is resulting in MethodNotFound exception.. Any pointers/patch available to get this solved - short of upgrading to Websphere 9?
Caused by: java.lang.NoSuchMethodError: javax/validation/Configuration.getDefaultParameterNameProvider()Ljavax/validation/ParameterNameProvider; (loaded from file:/opt/IBM/WebSphere/AppServer/plugins/javax.j2ee.validation.jar by org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader@25d460de) called from class org.springframework.validation.beanvalidation.LocalValidatorFactoryBean (loaded from file:../spring-context-5.0.2.RELEASE.jar by com.ibm.ws.classloader.CompoundClassLoader@1c7dbdd9
The method javax/validation/Configuration.getDefaultParameterNameProvider was added in Bean Validation 1.1, so that indicates the Spring Validator you are using is attempting to use the Bean Validation 1.1 API. According to https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/validation/beanvalidation/LocalValidatorFactoryBean.html:
As of Spring 5.0, this class requires Bean Validation 1.1+
WebSphere 8.5.5 provides Bean Validation 1.0 and did not add support for Bean Validation 1.1 until version 9.0. So, you'll either need to use Spring 4.x or WebSphere 9.x.
