Interesting. Can you tell how the hgupdater tool reacts to merges? 

a) If you merge 2 repositories and both contain a fix for the same bug (that is, JBS backport items exist) - will hgupdater just ignore the incoming changeset? Or will an additional JBS backport item be created?
b) Imagine the following situation: repository jdk11u is set up for 11.0.3 fixes and jdk11u-dev is set up for 11.04. jdk11u contains a fix for issue A and hgupdater had created a JBS backport item for 11.0.3. At the moment we'd merge back 11u -> 11u-dev the fix for A will land in 11u-dev. Would hgupdater then create an 11.0.4 backport item?

Thanks
