[SEVERE] Could not pass event EVENT_HERE to PluginNameHere?

I get some console spam errors, for more than one plugin and I'm not sure where to post for help, so here are the full console errors:

Code:

Any ideas?

 

plugin not compatable

 

@jsgage But the plugins work perfectly fine, even though these errors show. So they are compatible...

 

Im on the understanding the most plugins are not fully compatable until bukkit releases a Recommended Build

why not ask the author

 

@jsgage I have asked both authors, waiting on a reply. I just assumed it was bukkit in general as it's happening with more than one plugin.

 

here is a little deatil on what im playing with at the said time
2 Different setups "not runing at same time "

1 using bukkit b-1467 http://ci.bukkit.org/job/dev-CraftBukkit/1467/
Plugins:
wormholeextreme 1.011
backup 1.8.3
DefaultCommands 3.7.0
Permissionsbukkit 1.2
toucharrow 0.8
worldedit b-529
wormholeextremeworlds 0.505

This setup was what i was using before i upgraded my minecraft to 1.0.0, apart updating bukkit
now i connect with my 1.0.0 minecraft havent had errors seems to running fine so far.
The other setup is

2 using bukkit -b1518 http://ci.bukkit.org/job/dev-CraftBukkit/1518/
Plugins:
wormholeextreme 1.011
backup 1.8.3
creeperheal 4.2.2
Permissionsbukkit 1.2
toucharrow 0.8
worldedit b-529
wormholeextremeworlds 0.505

i added creeperheal plugin also had to repace defaltcommands plugin as not compat
with bukkit -b1518 replaced with CommandBin 1.32 for now, but are going back to
defaultcommands just as soon as its updated as it this plugin ive had trouble with
ever since updateing to minecraft 1.0.0
today im going to have a play with bukkit 1529 and my setupup of plugins
as nothing to do realy till bukkit updtae to recommended build ,that what most pluging
devs are waitin on.

ps just as it all gets updated bukkit+plugins minecraft will update again lol
