Old code behavior:
```
if (ndi instanceof UnifierDeployInfo) {
OperatorContext unifiedOperatorContext = new OperatorContext(0,
((UnifierDeployInfo)ndi).operatorAttributes, containerContext);
} else {
parentContext = containerContext;
}
OperatorContext ctx = new OperatorContext(ndi.id,
ndi.contextAttributes, parentContext);
```
In the new code, the constructor handles which attributes to use.
```
public OperatorContext(@NotNull OperatorDeployInfo operatorDeployInfo,
Context parentContext)
{
super(operatorDeployInfo instanceof
OperatorDeployInfo.UnifierDeployInfo ?
((OperatorDeployInfo.UnifierDeployInfo)operatorDeployInfo).operatorAttributes :
operatorDeployInfo.contextAttributes,
parentContext);
}
