After upgrading to 2404.1.0, Trying to debug version 1.7 code fails with an unsupported version error: 52 (1.8). However, an exported runable jar file runs fine on an XP system that only supports 1.7. All projects have the proper jre settings for 1.7. This code was debuggable prior to the upgrade. Any suggestions?

Don,

Quite a few variables here. Trying to figure out if the problem is with debug or with compilation. There could be a difference between export and debugging against .class files built in-workspace because of the different processes involved.

I’m assuming the 1.7 code you’re trying to debug is also being built with MyEclipse 2024.1? First thing that comes to mind, can you check Preferences > Java > Installed JREs and confirm that the correct JRE is your workspace default? There is a new setting there that might have changed it, which could affect your compilation if your project is set to use the default JRE.

If we ignore debug, without exporting the JAR, are you able to launch application with a 1.7 JRE from the MyEclipse workspace with a launch configuration?

Finally, can you share a screenshot of the Project properties > Java Compiler page? I’m assuming this is where you have the 1.7 settings?

Thanks!
