Parsing @type has optional literal is failed on demo about doctrine

[Constellation]

Thanks for your report.
Yes, this is the behavior by spec. Probably I think this is the same behavior to Google Closure Compiler, right?

@type {foo=}

Should be @type {foo|undefined} instead.

Hmm, I received an error with Closure Compiler trunk.

Thanks, @Constellation and @tschaub !

I missed what official document was said.

herefore if the method stores the parameter's value in a class property, the type declaration of that property must include a possible value of undefined

I understand that = is accepted on only @param.
