Tim Allison commented on TIKA-4137:
-----------------------------------
Oh, wow. Interesting. So it isn't a general problem -- Java 21 forbids writing
a zero-length array of chars. Rather it's a problem with our transformer
configuration. Thank you so much. I'll close the initial PR, and open one for
this fix. That would explain why so many tests passed and we were only seeing
problems in some tika-server tests.
