Suhov Roman updated ARTEMIS-4932:
---------------------------------
Description:
*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;_
_}_
_}_
