Hi,
when I run ecb-activate the following error occured:
ECB 2.50 uses CEDET 2.0 (contains semantic 2.2, eieio 1.4, speedbar 1.0).
helm-M-x-execute-command: Symbol’s function definition is void: eieio--defgeneric-init-formUnable to load color "headerColor"

The previous emacs version 28.x doesn't have this issue.
Please advise how to fix.

Thanks,
Igor
