Glue In My Leather Jacket?

[user290389023]

I noticed that there is glue in addition to the sewing thread inside the collar, and cuffs, basically everywhere where leather meets leather...

Is this normal?

I don't know about normal but I think some manufacturers use glue on some seams which eases the sewing process but makes future repairs difficult if not impossible.
It is discussed in dudewuttheheck's blog as below

Lots of manufacturers use glue.

Yes- glue can be used to assist in hammering down seams. It tends to be reasonably soft-setting and can be prised apart from leather without too much trouble. Leather is skived, glued and hammered by several major manufacturers.

It isn't an indication of of quality (or lack thereof)- it's just a technique. Taping seams is relatively common.
