GroovyScriptEngineFactory not accessible from Eclipse RCP [message #1701106]

I have created an eclipse plugin that contributes a tool bar action. This plugin has dependency on groovy plugin 'org.codehaus.groovy'.

Here is my action command:

public void run(final IAction action) {
    ScriptEngineManager scrEngMgr = new ScriptEngineManager();
    List <ScriptEngineFactory> factories = scrEngMgr.getEngineFactories();
}

On execution of this command from RCP, in the list of ScriptEngineFactory, I do not get the GroovyScriptEngineFactory.

Looks like the RCP is not able to access the groovy jar exported by the groovy plugin.
I checked the source of groovy plugin 'org.codehaus.groovy' and see that in the MANIFEST.mf, all packages are exported and also lib/groovy-all-a.8.6.jar is added in the classpath.

Just for testing sake, in the same plugin, when I tried to run the same piece of code in a test class with a main() as a Java application, I do get the GroovyScriptEngineFactory from ScriptEngineManager.

Any clue on how to access GroovyScriptEngineFactory in an RCP?

Are all of its dependencies met by your RCP application?

Attached is my test plugin 'com.test.groovy'. The target in my Eclipse platform has 'org.codehaus.groovy' plugin in it.
When I debug as Eclipse Application with the attached test plugin, with a breakpoint set in run() of class SampleAction, on click of the toolbar icon 'Hello, Eclipse World', I do not get GroovyScriptEngineFactory Confused

I am attaching the target Groovy plugin 'org.codehaus.groovy' also for your reference.

In the OSGI console of the launched application, I am able to see both my test plugin and its dependent Groovy plugin in RESOLVED state
