Hi Petr,

Looks fine to me, thanks for fixing this.

One comment - perhaps it'd be better to synthesize one UP event. 
According to the spec, the Plugin doesn't receive DOWN/UP events 
associated with composition - the Plugin receive one DOWN event and 
returns kNPEventStartIME to start composition and we should probably 
synthesize one UP event for consistency.

And it seems like Glass works the same way - synthesize one UP event 
associated with composition:

GlassEmbeddedWindow+Npapi.m (_1dispatchCocoaNpapiTextInputEvent function)

        if ([chars length] == 1) {
                env, jNpapiClass, jPtr, 
                0, jText, jText, JNI_FALSE, 0, JNI_FALSE);
