to to get the value for thisObj argument when invoking call(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable, org.mozilla.javascript.Scriptable, java.lang.Object[]). The methos
is allowed to return null to indicate that call(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable, org.mozilla.javascript.Scriptable, java.lang.Object[]) will create a new
object itself. In this case construct(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable, java.lang.Object[]) will set scope and prototype on the result
