Norman Maurer 106bd0c091 DefaultFileRegion.transferTo with invalid count may cause busy-spin (#8885) ... Motivation: `DefaultFileRegion.transferTo` will return 0 all the time when we request more data then the actual file size. This may result in a busy spin while processing the fileregion during writes. Modifications: - If we wrote 0 bytes check if the underlying file size is smaller then the requested count and if so throw an IOException - Add DefaultFileRegionTest - Add a test to the testsuite Result: Fixes https://github.com/netty/netty/issues/8868.		2019-02-26 11:21:03 +01:00
