I'm using Flamingo Ribbon Bar in a NetBeans project, and I'm having a major issue with it: sometimes (I'm sorry I can't be more specific since I really can't figure out how to consistently replicate it) I get the following exception:
Java.lang.IllegalArgumentException: No interpolator found for java.lang.Float:java.lang.Float

with the ribbon bar not initializing (and thus my software being unusable). Sometimes, If I close it and restart it, it starts correctly, some other times not. I'm not having the slightest idea of what's happening; somewhere I read something about a wrong classloader being used but I can't really find that link now... Can anyone please help? Of course I can provide more details if needed
Thanks
Although the accepted answer could have done the job, this is not the correct approach. Basically, the above is a workaround for a problem that shouldn't be/isn't there in the first place. Because of many source and binaries transfers of the trident library, it has happened so that a very important file's been left behind. Thus spreading the bug like a virus.
The file is called trident-plugin.properties and, flabbergastingly, there are stored the location of the available interpolators.
So, the obvious fix would be to add this file to the affected package in the META-INF directory.
For quick reference, here are the contents of it:
