IDEA bug? UnsupportedOperationException: Not implemented

It seems that JTextPanes created with the UI Designer have editor actions assigned but not defined.
i noticed this bug in my project, but it also happens inside IDEA itself, e.g. inside the search-field of the settings dialog-
pressing CTRL+Y inside a JTextPane throws the following error:

It seems that this is a bug inside the IntelliJ IDEA Open API itself, or is there a way to avoid this error in my own project, e.g. by disabling/reassigning the key/actionmap?

Thanks,
