Description

Reproduction line:

./gradlew test --tests TestDirectIODirectory.testFloatsUnderflow -Dtests.seed=73B56EAB13269C91 -Dtests.slow=true -Dtests.badapples=true -Dtests.locale=haw-US -Dtests.timezone=America/Inuvik -Dtests.asserts=true -Dtests.file.encoding=UTF-8

I didn't have the chance to look deeply, but it seems like the wrong exception type is being thrown:

 junit.framework.AssertionFailedError: Unexpected exception type, expected EOFException but got java.nio.BufferUnderflowException
