Invalid cache key in AnnotationActionValidationManager.buildValidatorKey when using visitor field validators

Error scenerio:

MyAction-validation.xml:
<validators>
<field name="myField"> <!-- MyClass -->
<field-validator type="visitor">
<param name="context">basic</param>
<param name="appendPrefix">true</param>
<message/>
</field-validator>
</field>
<field name="myField">
<field-validator type="visitor">
<param name="context">additional</param>
<param name="appendPrefix">true</param>
<message/>
</field-validator>
</field>
</validators>

In this case, validators in MyClass-basic-validation.xml will be executed two times, but validators in MyClass-additional-validation.xml will just ignored.

The problem is caused by AnnotationActionValidationManager.buildValidatorKey(Class) which returns the same cache key for the validator cache.

The current cache key is created by:

StringBuilder sb = new StringBuilder(clazz.getName());
sb.append("/");
sb.append(proxy.getConfig().getName());
sb.append("|");
sb.append(proxy.getMethod());

The context is not a part of the cache key. Therefore, the two visitor validator will just get the same cache key.
