We try to avoid causing StackOverflow, but it was possible
to trigger one here with a specially crafted input-file.

This puts a limit on the number of nested children in place
and logs a warning when the Stream is not fully parsed.

Some CI runs seem to throw the exception with an empty message instead of 
the expected text.

I could not reproduce this consistently and so we only can disable a
check in this case.

It seems doing it this way can kick in even when using JDK 11+ due 
to the Gradle toolchain.

Let's rather do a more specific exclusion in code to only exclude files
which actually cause JDK 8 to hang.

We try to generally avoid overly large allocations in places
where arrays are allocated. 

We add one more such check for pictures in HSLF.

We might need to increase the used value of 10MB if users report 
larger files being used frequently. 

Overriding this check via IOUtils is possible.

Otherwise there is lots of output that is likely rarely useful. 

This can be changed locally for testing easily whenever necessary.
