OutOfMemoryError introduced by 1.1.0

[cchantep]

After upgrade, it seems that 1.1.0 introduce an OOM.

May be related to #454

@cchantep do you still have this issue in 1.2.0? I've noticed the same thing going from 1.2.0 to 2.0.0, suddenly uses twice more Java heap memory. (from 3G up to 7G)

[cchantep]

Still issues with latest 2.1.1 :
