Justin Bertram updated ARTEMIS-4932:
------------------------------------
Description:
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}

*A problem has been detected in the URISchema file.java 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().
For example, you could change the code like this:
_if (defaultFactory != null && uri.getHost() == null) {_
_String defaultScheme = defaultFactory.getScheme();_
_if (defaultScheme != null &&_
_defaultScheme.equals(uri.getScheme())) {_
_uri = defaultFactory;_
_}_
_}_
> Reference, returned from function 'defaultFactory.getScheme()String' at
> URISchema.java:53, may be null and is dereferenced at URISchema.java:53.
