iReport 5.1.0 was built to run on Java 6 or Java 7. If you try to launch it with a modern Java version (like Java 17 or 21), it will crash immediately.
Many government and financial institutions are still running Java 7 (or even Java 6). iReport 5.1.0 runs flawlessly on older JDKs, whereas modern reporting tools require Java 8 or 11. If you cannot upgrade your JVM due to bureaucratic red tape, 5.1.0 is your lifeline.
