NPE in AccessTokenRequestParams#addExtraParameters method #1082
Description
The method throw NullPointerException each time that it call when the class variable extraParameters is null because the initialisation is done for the parameter variable and not for the class variable with the same name. The this. is missing.
public AccessTokenRequestParams addExtraParameters(Map<String, String> extraParameters) {
if (extraParameters == null || extraParameters.isEmpty()) {
return this;
}
if (this.extraParameters == null) {
extraParameters = new HashMap<>(); // Error
}
this.extraParameters.putAll(extraParameters);
return this;
}
It should be :
if (this.extraParameters == null) {
this.extraParameters = new HashMap<>();
}
