java.lang.NoClassDefFoundError And really this is curious :P

Heyho Community,

I have a yeah major bug:

I have this class: https://github.com/SacredCoding/Sim.../simpleclans/managers/SpoutPluginManager.java
It contains simple spout features.

And I call it here: https://github.com/SacredCoding/Sim...yrinth/phaed/simpleclans/SimpleClans.java#L85

Now the curious thing:
It throws a NoClassDefFoundError. If I remove the sendInfo() all works. So basically I do nothing if spout isnt found.

Here is the exception:

Code:

14:30:53 [SEVERE] Error occurred while enabling SimpleClans v2.4 (Is it up to date?)

Hm maybe ill move all this in another class....

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I am having this error too sometimes when i enable my plugins on my server.
Restarting the server helps, and solves the problem for me.

It is really weird...

My Server is using:
Java 6
Windows XP

 

I fixed it now by loading the class only if spout is installed.
