checkup.atlassian.com reports unavailable fields?

[Deleted user]

So I'm looking at the very handy checkup.atlassian.com, but get one field that is being reported as unavailable:

Checkup says the following is unavailable:

Usages SummarySystemField#MAX_LEN:Long
AbstractFieldProcessorFixer#fixupSummary(Map):void where the field is read.
AbstractFieldProcessorFixer#fixupSummary(Map):void where the field is read.

Yet, the 5.2-m05 source bundle begs to differ:

public static Long MAX_LEN = 255L;

So, question: what is checkup telling me?

Well, a poke is not getting a response, and I can't poke again, so bumping with a comment. Would love to make use of the information provided from checkup, if I could understand it.
