But this issue should be addressed—it's similar to a zip bomb, where small but valid source data can consume a huge amount of memory after processing. To handle this, we should convert a fatal OutOfMemoryError into an IOException, which the application is likely already expecting.

It's unlikely that throwing an IOException will also cause an OOM, since before the new exception is thrown, the GC will clean up, freeing the allocated multi-gigabyte data in this block.
