Hi Nirmal, Sorry for the delay! I needed some time to go through the coding guidelines in WSO2 and other Apache project.
All, Since everyone agrees on 4 spaces, we will configure that accordingly. My next concern is that 100 columns for a line is too short. Most of other projects use 120 columns for the line width. For example: http://maven.apache.org/developers/conventions/code.html https://airavata.apache.org/development/source.html http://onami.apache.org/committers/codestyle.html However I think it's better if we can have at least 160 columns for a line. There are some projects, which use 160 columns. :) https://accumulo.apache.org/source.html So, WDYT?
