Hi, when I'm try to run the RCPTT Application Eclipse in my Eclipse 2022-06 (4.24) then the following error occurs:

An internal error occurred during: "Launching RCPTT_OUT_2022-06_03".
java.lang.NoSuchMethodError: org.eclipse.pde.internal.launching.launcher.LaunchValidationOperation.<init>(Lorg/eclipse/debug/core/ILaunchConfiguration;)V
at org.eclipse.rcptt.launching.internal.target.TargetPlatformHelper$1.<init>(TargetPlatformHelper.java:462)

This did NOT happen with last Eclipse version 2022-03 in combination with RCPTT nightly build 2.5.2.202204202359 but now with 2022-06 it does not work anymore with the following nightly builds:
2.5.4.202205041425, 2.5.3.202204301151 and 2.5.2.202204202359

I hope somebody has an idea :-)

Thanks in advance.

P.S: Now I found a Bugzilla Bug 580261 that explains the same issue I have noticed with Eclipse 4.24 with RCPTT:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=580261
The reporter added also a pached version for the launcher 2.53 so that it possible to use RCPTT with Eclipse 2.24. But I found also other issues with RCPTT in this Eclipse version - when I run the tests then the log is full from reflection exceptions and the AUT needs much more heap memory :-(
