I think this problem is from REI compatibilities.
Can you send report to REI dev first?
I will fix when If they says it is not REI's fault.

This is not REI's fault as the class is not a part of the JEI API spec. Use another way to get the gui pos, the JEI internals way is not the way.
Alternatively you can enable the Forge REI integration and disable the REI's JEI compat layer by following shedaniel/REIPluginCompatibilities-Issues#23 (comment)
