I need a fix/workaround in 0.14.0 version as I can not upgrade the version in
my product.

I am very sorry :(, but we cannot maintain several versions of the library due
to the extremely limited manpower we have. Furthermore 0.14.0 is an extremely
old version which contains many bugs that have been fixed since. I do strongly
recommend to make the effort and upgrade to 2.1 :) (unless you cannot use JDK
1.8 code, in which case I cannot offer a solution).
