Since you downloaded the latest Eclipse (2025-09), it's possible that Eclipse hasn't fully caught up with Java 25 yet, even if it officially supports it. Eclipse's support for a new Java version often lags behind the JDK's release. One thing you could try is ensuring you have the latest version of Eclipse installed (including any updates for the Java tools).

• Go to Help > Check for Updates to make sure everything is up-to-date, especially for Java-related tools

Also check the java 25 JDK Path in eclipse.ini file

Try setting the -vm parameter directly to the Java 25 JDK instead of a specific library within it.

In your eclipse.ini file, it should look something like this:

• /Library/Java/JavaVirtualMachines/temurin-25.jdk/Contents/Home/bin/java

make sure this is in different line than -vmargs, and ther are no extra spaces.

Check Java Version Using Eclipse Console:

Once you have made these changes you can check what Eclipse is using by openning the eclipse console and running this commend in the Eclipse IDE treminal or checkking the version in the console:

• java -version

This will confirm if the environment is pointing to Java 25 or still using the older version.
