I'm new to play and upgrading a play 2.0.x app to play 2.5.x,

getting following exception, on loading application after "activator run" and loading localhost:9000 from browser

play.api.UnexpectedException: Unexpected exception[UnsatisfiedDependencyException: Error creating bean with name 'interface be.objectify.deadbolt.java.cache.PatternCache': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'play.cache.CacheApi' available: expected single matching bean but found 2: interface play.cache.CacheApi,interface play.cache.CacheApi qualified with QualifierInstance(@play.cache.NamedCache(value=play))]

I've following findings
play.cache.CacheApi has two implementations annotated with @Singleton

1. public class DefaultCacheApi implements CacheApi {} (in "play.cache" package)
2. class EhCacheApi @Inject() (cache: Ehcache) extends CacheApi (in "play.api.cache" package in Chache.scala)

how to provide dependency in spring using play 2.5.x,

using following deadbolt entry in build.sbt

"be.objectify" %% "deadbolt-java" % "2.5.4",

note: spring is loaded using https://github.com/remithieblin/play-spring-loader,
