Tough one. I assume we want to return 'null' when trying to read an invalid or unsupported file, but fail outright in case of an I/O problem. This sounds like a type of "I/O problem", but, it does appear to arise when the data was read just fine but the data isn't supported or doesn't make sense: https://github.com/frohoff/jdk8u-dev-jdk/blob/master/src/share/classes/com/sun/imageio/plugins/jpeg/JPEGImageReader.java#L1068 So yes this seems reasonable. yes, weird that it happens only sometimes in a test though ... maybe a corrupted checkout on a worker? After this, we'd be unexpectedly getting a null for some image in this test - is that just irrelevant for the test? -- This is an automated message from the Apache Git Service.
