IncompatibleClassChangeError error

[Sonal Jogi]

Hi,

I am getting this error in my log files. Could anyone please indicate me the source of this error? I am not using 'DefinitionsFactory' in any of the class implementations and this error has come out of blue otherwise the site was not giving any error.
