[jdk21u-dev] RFR: 8319598: SMFParser misinterprets interrupted running status

Thu Aug 7 02:28:00 UTC 2025

Backporting JDK-8319598: SMFParser misinterprets interrupted running status. The MIDI file parser misinterprets events without status byte when they appear directly after a Meta of SysEx event. This fix uses the status of the last channel event as running status, which is the more conservative solution. Ran GHA Sanity Checks, local Tier 1 and 2 and new test directly. Patch is clean.
