RCPTT not usable with Java 23

[akurtakov]

Launching application when RCPTT is started with Java 24 leads to the following error. If the jvm for the app is changed to Java 21 via Configure/Advanced - it works.

For AspectJ to work correctly, the application should contain org.objectweb.asm of compatible version. AFAIK, most Eclipse packages carry an version incompatible with latest Java. RCPTT could correct this by injecting a compatible alternative. But I'm not sure where to find one.

This explanation is incorrect, as AspectJ uses bundled ASM.

See eclipse-aspectj/ajdt#67

Eclipse 2025-06 staging already contains modern org.objectweb.asm so the problem should go away in Eclipse staging AUT.
Please comment if the problem does not go away then or if RCPTT should be future-proofed to support Java newer than AUT.

@akurtakov RCPTT 2.6 will now try to find a JVM compatible with AUT among configured and autodetected.

This happens again. Eclipse Platform 2025-06 has org.objectweb.asm 9.8.0 and yet RCPTT 2.7.0 reports same error when launching it as AUT.
