Merge branch 'vladdu/jinterface_code_cleanup/OTP-12211' into maint
* vladdu/jinterface_code_cleanup/OTP-12211: fix warning: Socket's InputStream not closed silence 'potential resource leak' warnings don't warn about some unused fields/variables handle warnings about potential null pointers keep all method parameters final renamed method parameters hiding fields add 'break' statements to make compiler happy remove warnings from OtpMD5 rename OtpNode.flags to connFlags rename OtpNode.Acceptor.port to acceptorPort rename field 'self' to 'localNode' mark deprecated unused private constructor simplify 'if' statements remove warnings: @Override, switch fall-through make serialVersionUID fields private remove unnecessary syntax (casts) remove unused variables removed unnecessary semicolons, imports, labels remove unnecessary null pointer checks remove unnecessary Cloneable and Serializable
