> Key: ARTEMIS-4932
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4932
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.25.0
> Reporter: Suhov Roman
> Priority: Major
> Attachments: 1.png
>
>
> A problem has been detected in the {{URISchema.java}} file on line 53 and 70.
> In a call to the {{getScheme()}} method on a {{defaultFactory}} object,
> {{getScheme()}} may return {{null}} which will throw a
> {{NullPointerException}} when {{equals()}} is called.
> To avoid a {{NullPointerException}}, you should check the result of
> {{getScheme()}} for {{null}} before calling {{equals()}}, e.g.:
> {code:java}
> if (defaultFactory != null && uri.getHost() == null) {
> String defaultScheme = defaultFactory.getScheme();
> if (defaultScheme != null && defaultScheme.equals(uri.getScheme())) {
> uri = defaultFactory;
> }
> }{code}
