Vitaly Davidovich reports an IllegalStateException when inspecting a JarFile's contents using a parallel stream:

java.lang.IllegalStateException: Current state = CODING_END, new state = FLUSHED
               at
java.base/java.nio.charset.CharsetDecoder.throwIllegalStateException(CharsetDecoder.java:998)
               at
java.base/java.nio.charset.CharsetDecoder.flush(CharsetDecoder.java:681)
               at
java.base/java.nio.charset.CharsetDecoder.decode(CharsetDecoder.java:810)
               at
java.base/java.util.zip.ZipCoder.normalizedHashDecode(ZipCoder.java:136)

This is due JDK-8243469 which changed the UTF-8 ZipCoder code to use a shared CharsetDecoder, which is not legal.
