### Question
```java
public static String getMessageFromThrowable(Throwable throwable) {
if (throwable == null) {
return "throwable is null, unknown error.";
}
String message = null;
Throwable cause = throwable.getCause();
if (cause != null) {
message = cause.getMessage();
}
if (message == null || "".equals(message)) {
message = throwable.getMessage();
}
if (message == null || "".equals(message)) {
message = throwable.getLocalizedMessage();
}
if (message == null || "".equals(message)) {
message = throwable.toString();
}
if (message == null || "".equals(message)) {
message = "unknown error.";
}
return message;
}
```
I'm curious about the intention behind the conditional statement, as
ultimately, if 'message' is null, it ends up containing 'unknown error'. I was
planning to remove the conditional statement through this PR, but I wanted to
ask if it might have been created for future use or another purpose.
