I'm having a similar issue, but it throws a different runtime exception, with the Stack Trace having the same code:

@andyparkerson I'm having the same issue. Any luck with the solution?

[TiBeN]

I had the same issue. It seems the Exception is triggered by phpdocumentor while scanning comments blocs. As a workaround "<" chars from comments in your code have to be removed. Typically in my code i had comments like this:

/**
* [..] 
* @param <type> myVar
*/

<type> is what makes throwing this exception. But this is just a workaround and this is not really satisfying from a user perspective as code support tools like php language server have to handle theses cases like displaying a warning, not break.
