RFR: 8355371: NegativeArraySizeException in print methods in IO or System.console() in JShell

[Tatsunori Uchino]

This PR will fix not only JDK-8355371 but also JDK-8354910. I chose the more serious one.

Note: according to JEP-512 (JDK-8344699), java.io.IO is going to stop using System.console().
I confirmed it by checking out and building https://github.com/openjdk/jdk/pull/24438. (in that PR, the bug does not occur in `IO.print(ln)`)

Before (Temurin 24):


jshell> IO.println("a".repeat(128))
Exception in thread "output reader" java.lang.NegativeArraySizeException: -128
|  State engine terminated.     at jdk.jshell/jdk.jshell.execution.impl.ConsoleImpl$ConsoleOutputStream.readCharsOrNull(ConsoleImpl.java:486)

        at jdk.jshell/jdk.jshell.execution.impl.ConsoleImpl$ConsoleOutputStream.write(ConsoleImpl.java:402)
        at java.base/java.io.OutputStream.write(OutputStream.java:167)
|  Restore definitions with: /reload -restore
        at java.base/java.io.OutputStream.write(OutputStream.java:124)
        at jdk.jshell/jdk.jshell.execution.DemultiplexInput.run(DemultiplexInput.java:74)

jshell> IO.println("ドラえもん")

jshell> System.console().writer().println("a".repeat(128))
Exception in thread "output reader" java.lang.NegativeArraySizeException: -128
        at jdk.jshell/jdk.jshell.execution.impl.ConsoleImpl$ConsoleOutputStream.readCharsOrNull(ConsoleImpl.java:486)
|  State engine terminated.

jshell> System.console().writer().println("ドラえもん")

After (master & without https://github.com/openjdk/jdk/pull/24438):


jshell> IO.println("a".repeat(128))
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

jshell> IO.println("ドラえもん")
ドラえもん

jshell> System.console().writer().println("a".repeat(128))
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

jshell> System.console().writer().println("ドラえもん")
ドラえもん


I don't know how to prepare the template other PRs use or whether outsiders like me may create a PR.
