: does not get converted to _ #1548
Description
From @shakuzen in micrometer-metrics/micrometer#6644 (comment):
it seems : does not get converted to _ in 1.4.1 but it did in 1.3.10. Is that change intentional?
This breaks the Micrometer build, see micrometer-metrics/micrometer#6644 and micrometer-metrics/micrometer#6644 (comment) for more details and reproducing tests.
