I want to process huge flat file having 50k to 100k records, with fix positional mapping.
There two identical files with minor different and have logical relation. 

Do you know if there is any third party app or library which can support loading of such flat files into system?

There is a good java library JavaCC which can help you in parsing flat files.

javaCC uses regular expressions.

However, if it is a fixed position file,  where you know the start and end location of strings to capture, then I will recommend to use simple IO to read flat file and string buffer to read line by line and using string tokenizer to capture data.
use buffered IO reader here,
