Current state = CODING_END, new state = FLUSHED?

[Jaikiran Pai]

Hello Peter,

Looking at the linked issue and the stacktrace presented there, this 
appears to be related to java.util.zip code.  I've moved this thread to 
core-libs-dev which is where discussions related to java.util.zip happen.

The stacktrace is as follows:

Caused by: java.lang.IllegalStateException: Current state = CODING_END, 
new state = FLUSHED
     at java.nio.charset.CharsetDecoder.throwIllegalStateException 
(CharsetDecoder.java:998)
     at java.nio.charset.CharsetDecoder.flush (CharsetDecoder.java:681)

     at jdk.internal.loader.URLClassPath$JarLoader.getJarFile 
(URLClassPath.java:816)


Additional details in that issue state that the JDK being used is Java 
15. There have been code changes in this piece of code in 
java.util.zip.ZipFile since then. In fact, in the current mainline (and 
recent releases) I don't see initCEN calling the ZipCoder. Would you be 
able to test this against more recent releases (preferably Java 19) and 
see if it is still reproducible?
