NPE if null argument specified for InternetHeaders.getMatchingHeaders()
-----------------------------------------------------------------------
Key: GERONIMO-4126
URL: https://issues.apache.org/jira/browse/GERONIMO-4126
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Reporter: Rick McGuire
Assignee: Rick McGuire
Priority: Minor
Fix For: 2.2
The InternetHeaders getMatchingHeaders(), getNonMatchingHeaders(), etc. methods
give an NPE if a null match list is provided. The Sun implementation treats
this the same as an empty array. The following simple program can demonstrate
the problem:
import javax.mail.internet.InternetHeaders;
import javax.mail.Header;
import java.util.Enumeration;
public class TestMatchHeaders
{
static public void main(String [] args) {
InternetHeaders headers = new InternetHeaders();
headers.setHeader("Subject", "Hello");
headers.setHeader("From", "Me");
Enumeration e = headers.getMatchingHeaderLines(null);
System.out.println(">>>>> Matching lines");
while (e.hasMoreElements()) {
System.out.println((String)e.nextElement());
}
e = headers.getNonMatchingHeaderLines(null);
System.out.println(">>>>> Non-Matching lines");
while (e.hasMoreElements()) {
System.out.println((String)e.nextElement());
}
}
}
