Custom interceptor with Position.OTHER_THAN_FIRST_OR_LAST causes CacheManager start to fail

Use case (done via declarative config, but doesn't matter):
1) Add CustomInterceptor1 with position="FIRST"
2) Add CustomInterceptor2 with position="LAST"
3) Add CustomInterceptor3 with position="OTHER_THAN_FIRST_OR_LAST"

Expected that order of interceptors 1, 3, 2, or at least it would work. Unfortunately, this configuration fails during start of CacheManager with:

org.infinispan.commons.CacheConfigurationException: ISPN000225: Custom interceptor 'testpackage.CustomInterceptor3' doesn't specify a position

Thus (and by looking at the code), option OTHER_THAN_FIRST_OR_LAST doesn't do anything.
