[rules-users] Is there any limitation about the length of attribute's name when declare type in drl file

[Davide Sottara]

"Declares" are compiled into java classes, so the only limitations would
be posed by the JVM.
I tried to run your snippet, but it works fine (you should still follow
conventions and use upper case
names for the declared types).
The CCE you get, moreover, seems to point to a different issue.
Could you post a full reproducer, together with details on your
environment - Drools version, JVM, OS, etc...
Thanks
Davide
