+++ This bug was initially created as a clone of MDSAL-84 +++

I am reading the code under ALTO@ODL. And here are my two comments.

1:File named ‘AltoProviderImplBuilder’under alto-provider/……./modules/module/configuration :in function named 'toString',first is defined to judge a common should be inserted, i recommend writting as following

@Override
public java.lang.String toString() {
java.lang.StringBuilder builder = new java.lang.StringBuilder ("AltoProviderImpl [");
//boolean first = true;

if (_dataBroker != null) {
//if (first)

else

builder.append("_rpcRegistry=");
builder.append(_rpcRegistry);
builder.append(", ");//new added

}
//if (first)

else

builder.append("augmentation=");
builder.append(augmentation.values());
return builder.append(']').toString();
}
}
Fewer judgement, fewer jumpes and simplified, consistent code,Make sense. There are similar something in file named RpcRegistryBuilder.java under alto-provider/……../modules/module/configuration/alto/provider/impl

BTW,could anyone tell me who is responsible for the improvements
