JetBrains / jdk-sa-jdwp Duplication

JetBrains / jdk-sa-jdwp

Places in code with 6 or more lines that are exactly the same.

Intro

For duplication, we look at places in code where there are 6 or more lines of code that are exactly the same.
Before duplication is calculated, the code is cleaned to remove empty lines, comments, and frequently duplicated constructs such as imports.
You should aim at having as little as possible (<5%) of duplicated code as high-level of duplication can lead to maintenance difficulties, poor factoring, and logical contradictions.
