new c94db5ee JOHNZON-421 Defer start of object/array
c94db5ee is described below
commit c94db5ee3cd0864fb749e0445b264aa662aaad4b
Author: Mark Struberg <[email protected]>
AuthorDate: Wed Feb 11 15:00:46 2026 +0100
JOHNZON-421 Defer start of object/array
This is necessary as we don't know what Serializers/Adapters/Converters
actually do write.
If we start an object with { and the JsonbSerializer just writes a string
value (json primitive)
then we will blow up. Deferring the start fixes this issue.
