#241 Java 25 is not detected

Hello,

there appears to be a problem detecting Java version 25. If the current version 25.0.0 is specified as the minimum version, the application will not start. The log file reads:

FYI: The version 25.0.1 is correctly detected. Perhaps it is just a problem with the comparison operator "greater than" or "greater than or equal to".

Thank you for posting all the details, this indeed could be a comparison
problem.

Best regards,
Grzegorz
