Thanks for quick answers guys!

I just realized the original thread never made it trough to the list (the user didn't register probably) the original poster had the same issue on Guvnor, hence the title.
Edson I've opened https://issues.jboss.org/browse/JBRULES-3621 for this

Unfortunately, I don't have any workaround for this, as I don't know beforehand the structure of the POJO to use (in my use case, there is an additional layer on top of drools, and I don't know the facts).

Although I'm not 100% blocked by this, is it possible to reuse the drools code generator manually? That way I could workaround it by generating the class myself and skip the constructor generation?

a workaround could be to use a java pojo, not a declared fact

Ouch, more than 255 fields? As of 5.4.x there is no workaround, the engine always tries to generate the constructor.

Can you please open a JIRA and we will fix this for the next release?

Thank you,

Edson

Hi guys,

I just stumbled into the same issue in 5.4.0.Final, I think this is caused
by https://issues.jboss.org/browse/JBRULES-2652
When declaring a type, a constructor with all fields as parameters is
generated automatically, but this causes in our case to hit a barrier of the
Java language because the generated constructor has more than 255 parameters

Anyone knows if this generation can be skipped (annotation or something
else), maybe a safeguard not to generate the constructor when the limit is
reached would be nice too?
