That would then mean the loop in which this `deflate` happens, would never exit leading to the test timing out.

The use of fixed size here will not re-introduce the original issue which https://bugs.openjdk.org/browse/JDK-8299748 fixed, because unlike previously, this is just a temporary size and we continue to deflate the content into a dynamically growing `ByteArrayOutputStream` till the deflater is "finished".
