[jira] [Comment Edited] (MNG-6571) Maven memory consumption issue
[ https://issues.apache.org/jira/browse/MNG-6571?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16749950#comment-16749950 ]

[~mickael.istria] I hoped you'd be interested :)
FYI, I was yesterday at ParisJUG session https://www.parisjug.org/xwiki/wiki/oldversion/view/Meeting/20190121 and this pattern was one of the topics explained during the "Revisiting Effective Java in 2019" talk :)
for BigIntegers, VersionRange will drastically reduce the number of ComparableVersion instances
But you're right: we could probably optimize ComparableVersion code to check if the number parsed is small enough to be represented as an int or long: the biggest numbers we get usually is the timestamp of a SNAPSHOT, like 20171015.230843, then an int would be sufficient
