Media crash when playing MP3 over JRT protocol on macOS 26.

To reproduce this issue play any MP3 files over JRT protocol using FXMediaPlayer.

# A fatal error has been detected by the Java Runtime Environment:

# JRE version: Java(TM) SE Runtime Environment (24.0.2+12) (build 24.0.2+12-54)

This code was introduced with JDK-8287822 (jfx20) and was accidentally disabled by JDK-8282999 (jfx23) and enabled by JDK-8357714 (jfx25). So affected versions are starting with jfx20.

Note: This issue is intermittent. It takes about 1-50 tries to load MP3 before it crashes.
