Review comment:
Ah OK. That looks to be a tricky one now...
Would we like to apply strict length limit on the metadata location string,
so that StringUtils.abbreviate won't touch the abbreviated form of output?
It's a bit odd we try to abbreviate but apply soft limit & add some information
to the abbreviated form which leads to exceed the limit, and abbreviate again
to break the abbreviated form.
