Hi committers,

Please make sure to:
 - always commit with a message
 - always associate an issue number at the beginning of the message (unless you do style fixing)
 - always associate a readable message to the issue number that explain what is going on

It makes reading logs and follow what has change much easier.

Bad:
""
"stuff"
"HHH-1234"
"oops"

Good:
"style and import fixes in engine package"
"HHH-1234 Fix incompatibility with merge and nested collections"

Even Better:
"HHH-1234 Fix incompatibility with merge and nested collections

Collections at the second level used to be ignored (ie not copied over) when merge was used"
