Subject: [PATCH] Fix possible NPE (#8199)

this is a follow-up to #7043

I tried to add a test when that PR was opened:

*
https://github.com/trask/opentelemetry-java-instrumentation/commit/d2c6399a6ed4cc45e1c9a9a77c9e142d0f5c6575

but it doesn't really verify anything, since the NPE is throw/caught and
same behavior occurs
