Description

In XIncludeHandler's searchForRecursiveIncludes(), if the provided XMLLocator returns null for both getExpandedSystemId() and getLiteralSystemId(), an NPE will be thrown at the line:

if (includedSystemId.equals(fCurrentBaseURI.getExpandedSystemId())) {

Instead, if no location information is available, a more informative error or warning should be thrown to indicate that searching for recursive includes is not possible. In such a case, the method searchForRecursiveIncludes() should return false to allow processing to continue.
