Anything in the error log that looks relevant? Just to confirm I got it correctly, you are only seeing this in 4.26 and not in 4.25?

Thanks! Looks this warrants a bug. At this point, I am not sure whether this belongs in JDT or M2E, but since the exception has root in M2E, we can start with a bug there:
