/**
* This class acts as a delegate for all the available ScriptEngineManagers. Unluckily, the standard did not
* define it as an interface, so we need to extend it to allow polymorphism. However, no calls to super are used.
* It wraps all available ScriptEngineManagers in the OSGi ServicePlatform into a merged ScriptEngineManager.
*
* Internally, what this class does is creating ScriptEngineManagers for each bundle
* that contains a ScriptEngineFactory and includes a META-INF/services/javax.script.ScriptEngineFactory file.
* It assumes that the file contains a list of @link ScriptEngineFactory classes. For each bundle, it creates a
* ScriptEngineManager, then merges them. @link ScriptEngineFactory objects are wrapped
* into @link OSGiScriptEngineFactory objects to deal with problems of context class loader:
* Those scripting engines that rely on the ContextClassloader for finding resources need to use this wrapper
* and the @link OSGiScriptFactory. Mainly, jruby does.
*
* Note that even if no context classloader issues arose, it would still be needed to search manually for the
* factories and either use them directly (losing the mimeType/extension/shortName mechanisms for finding engines
* or manually registering them) or still use this class, which would be smarter. In the latter case,
* it would only be needed to remove the hack that temporarily sets the context classloader to the appropriate,
* bundle-related, class loader.
*
* Caveats:
* <ul><li>
* All factories are wrapped with an {@link OSGiScriptEngineFactory}. As Engines are not wrapped,
* calls like
* <code>
* ScriptEngineManager osgiManager=new OSGiScriptEngineManager(context);<br>
* ScriptEngine engine=osgiManager.getEngineByName("ruby");
* ScriptEngineFactory factory=engine.getFactory() //this does not return the OSGiFactory wrapper
* factory.getScriptEngine(); //this might fail, as it does not use OSGiScriptEngineFactory wrapper
* </code>
* might result in unexpected errors. Future versions may wrap the ScriptEngine with a OSGiScriptEngine to solve this
* issue, but for the moment it is not needed.
* </li>
