Package: libgcj9-0
Version: 4.3.2-2
Severity: normal

Hi,

import java.net.URI;

public class Test
{
    public static void main(String arg[])
      throws Exception
    {
        String a = "http://example.org/path";;
        String b = "http://example.org/path?q=query";;

        URI ua = new URI(a);
        URI ub = new URI(b);

        System.out.println( ua.equals(ub) );
    }
}

% javac Test.java && java Test
Exception in thread "main" java.lang.NullPointerException
   at java.net.URI.equals(URI.java:1215)
   at Test.main(Test.java:14)

I think the problem is in these lines:

    else if (!opaqueThis && !opaqueObj)
      {
        boolean common = rawPath.equalsIgnoreCase(uriObj.getRawPath())
->        && ((rawQuery == null && uriObj.getRawQuery() == null)
->            || rawQuery.equalsIgnoreCase(uriObj.getRawQuery()));
        if (rawAuthority == null && uriObj.getRawAuthority() == null)
          return common;

In ua.rawQuery is null but ub.rawQuery is not, so the expression in the
brace evaluates to false and the righthand side gets evaluated with
dereferences ua.rawQuery and this causes the NullPointerException. I
think you have to write something like this:

          && (rawQuery == uriObj.getRawQuery()
              || (rawQuery != null
                  && rawQuery.equalsIgnoreCase(uriObj.getRawQuery())));

Bye, Jörg.
