Re: Erratic nullpointer exceptions because feature structure has no type in Ruta

Hi Peter, There are no external AEs in our pipeline. We parallelise on the EC2 instances using multiple threads with the CPE, and we scale the EC2 instances using a custom AWS setup, but the EC2 instances are independent of each other, so that shouldn’t play a role. Cheers, Mario >

Re: Erratic nullpointer exceptions because feature structure has no type in Ruta

Hi, Ruta stores FS objects, but should of course clean them up when a new CAS is processed. We had some problems with wrong FS caused by a class loader switch. Do you use external analysis engines in your Ruta script? I actually do not think that one of those is the source of the problem
