Review comment:
I wonder why not do it via `this.sourceThread = new
LegacySourceFunctionThread(getName())` directly in master branch. Then
```
LegacySourceFunctionThread(String name) {
super(name);
}
```
Although `performDefaultAction` would be executed only once for source task,
it seems better to do it in constructor. WDYT?
