Like many JDK 1.1 era APIs, InflaterInputStream is very under-specified. In this case, the protected fill method is begging us to specify how it behaves when the input is at EOF. An I/O error is surprising here as it sets the protected len field to indicate EOF. We can't change it after 25 years so we will need to specify existing behavior. ------------- PR: https://git.openjdk.org/jdk/pull/9881
