Kinoshita > Priority: Major > Original Estimate: 24h > Time Spent: 4h 50m > Remaining Estimate: 19h 10m > > In some cases, the algorithm decides incorrectly when to which package names > to abbreviate. For example, abbreviating > {{org.apache.commons.lang3.ClassUtils}} to the length 18 will result > {{o.a.c.lang3.ClassUtils}} (22 characters) instead of {{o.a.c.l.ClassUtils}} > (18 characters as requested). The reason for this is that the algorithm > starts from the right and goes to the left abbreviating the packages and > starts to abbreviate the packages when it runs out of the available space. > Instead, the algorithm should start from the left and abbreviate all packages > that would result in a too-long string without abbreviating the package name. -- This message was sent by Atlassian Jira (v8.3.4#803005)
