Can't instantiate byte/long due to"Bad" conversion by ValueConverter [message #1794609]

Hi,
Please refer to the attached grammar where I am facing an issue with defining byte and long datatypes. When I try to specify an input like '1L' or '1b', Xtext fails validation and I get an error that says "[ERROR:For input string: "1b" (synthetic:/example.expression line : 1 column : 1)]". I suspect this has to do with a "Bad" conversion being done by one of the ValueConverters supplied by Xtext and this bug report cites the same

Am I correct regarding my error diagnosis? Should I be trying to wrap my head around implementing a custom value converter like here?

Thanks,
Rohit
