---------------------------------------------------------------
I have applied the change to fix this issue directly to [commit
251fde2|https://github.com/apache/jackrabbit-oak/commit/251fde23e03a4cc1d92e06a64ff6f52f619295f2]
in order to verified the fix. It runs to completion with {{-Xmx464m}} and it
runs OOM with {{-Xmx432m}}, i.e. just like before OAK-12040.
Below are the retained objects of the heap dump caused by this OOM for
comparison. For me this conclusively shows that the fix removes the regression
in heap usage.

> The change for OAK-12040 accidentally introduced increased heap usage,
> presumably due to the way the Azure SDK is invoked.
> Running all unit tests in {{oak-segment-azure}} via {{mvn clean test
> -Dtest.opts.memory=-Xmx496m -pl oak-segment-azure}} reliably causes an
> {{OutOfMemoryError}} (on my machine using java 21), which wasn't the case
> before this change.
