Revert "[perf] use precompiled pattern"

[volosied]

This reverts commit 5e56abd.

Binary compatibility tool reported that jakarta.faces.validator.BeanValidator changed:

I cannot recall if this is allowed (new field), but I think the specs needs to match 1:1.

Why not just make it private and duplicate it in the other class?

[tandraschko]

But propably not worth, im ok with revert
Please also port it master

I thought about that, but then I would have to declare the variable in three different classes and make it private.

So I opted to revert it for simplicity.
