Intercepting 401 error by MSAL during backend access

Question

In my project we acquire a token via MSAL in the main java application and provide this token in lots of different calls to a library (aka backend client) that handles the actual backend communication. By default, that works fine - until that token is invalid and then a 401 exception gets thrown that the library is unable to handle itself and forwards it as an exception to the main application (401 message - giving up).

I'd like to avoid surrounding each of those library call with a try-catch to handle it resulting in tons of redundant code here (if 401, get new token and use that). I'm more looking for a general way to handle all exceptions and just look for that 401 to get a new token and resume that function. So more or less a try-catch above a whole class with lots of functions + resume option. Maybe, it's also possible to intercept MSAL? Does Java actually support something like that? Any recommendations?
