Hi all,
im facing an issue, that when i deploy a WAR hook on a Liferay 7.3.4 GA5, that im getting the following error:
java.lang.LinkageError: loader constraint violation:  loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) previously initiated loading for a different type with name "javax/validation/ConstraintValidatorFactory"

I have added the library validation-api-1.1.0.Final.jar to ${lifery_home}/tomcat/lib/ext
and added the package javax.validation to the portal property module.framework.system.packages.extra

I am sure, that there is no other validation-api.jar inside the classloader hierarchy.
May you can help we, what i am doing wrong here.

Thanks & BR,
Philipp
