title: duplicate bundle in eclipse Mars Release (4.5.0)
body: <p>I use eclipse which version is Mars Release (4.5.0) to develop RCP application . In product definition file, I designated javax.servlet 3.1.0 bundle. But after I export product, I found a file javax.servlet_3.0.0_2011xxxx.jar in product plugins directory. It puzzled me a lot. Then I browse the Eclipse directory structures, and two jars exist in eclipse/plugins directories:   javax.servlet_3.0.0_2011xxxx.jar
  javax.servlet_3.1.0_2014xxxx.jar
     I'm confused why there are two javax.servlet bundles. Even if there are two bundles, I had designate a version 3.1.0, why export wizard copy a wrong jar file?</p>
