[DRE-maint] Bug#1033912: ruby-maven-libs: autopkgtest regression: output on stderr

Dear maintainer(s),

Your package has an autopkgtest, great. However, it fails since 
September 2022. Can you please investigate the situation and fix it? I 
copied some of the output at the bottom of this report. The test itself 
passes, but it prints on stderr. That is considered failure by 
autopkgtest unless the allow-stderr restriction is declared. (My 
copy/paste seems to be missing a character).

The release team has announced [1] that failing autopkgtest on amd64 and 
arm64 are considered RC in testing. [Release Team member hat on] Because 
we're currently in the hard freeze for bookworm, I have marked this bug 
as bookworm-ignore. Targeted fixes are still welcome.

More information about this bug and the reason for filing it can be 
found on
