Contribution permission and ignite-2196

[Наумов Алексей]

Hello!
I would like to contribute to apache ignite and i am asking for contribution 
permission.
I would like to start with ignite-2196 to get familiar with contribution 
process. The issue Is still reproducable (broken link from documentation -  
https://ignite.apache.org/releases/latest/javadoc/index.html). Im plannig to 
remove the link and wrap it into @code directive as suggested in comments to 
jira issue. Is this ok?
