[Bug libgcj/23183] New: SimpleDateFormat fails to render '' as single quotes

[hannes at helma dot at]

When using java.text.SimpleDateFormat to render a date, single quotes encoded as
'' (see <http://java.sun.com/j2se/1.3/docs/api/java/text/SimpleDateFormat.html>)
in the format string are swallowed in the output. The following code

   sdf = new SimpleDateFormat("''yyyy-MM-dd HH:mm:ss''");
   sdf.render(new Date());

produces something like this:

   2005-08-01 18:54:05

bug should actually produce:

   '2005-08-01 18:54:05'

Interestingly, using single quotes to escape other text works as supposed, and
using '' next to escaped text also causes the single quotes to appear. Thus, 

   sdf = new SimpleDateFormat(""'' '' '''FOO''' '' ''"");
   sdf.render(new Date());

produces:

    'FOO'

while it shold produce:

   ' ' 'FOO' ' '

PS: Maybe I should have reported this bug against Classpath, but I wasn't sure
which version of classpath is used in gcj 4.0.

Confirmed on the mainline which means classpath .17+.

Note: classpath's SimpleDateFormat has not been fully merged into libgcj.

Here is the complete test case:

import java.text.*;
import java.util.*;

public class pr23183 {
  public static void main(String[] args) {
    SimpleDateFormat sdf = new SimpleDateFormat("''yyyy-MM-dd HH:mm:ss''");
    // Should have quotes around it, but does not.
    System.out.println(sdf.format(new Date()));

    // should produce ' ' 'FOO' ' '
    sdf = new SimpleDateFormat("'' '' '''FOO''' '' ''");
    System.out.println(sdf.format(new Date()));
  }
}


This fails with both gcj 4.1 and classpath cvs head (0.17+)

I checked this in to classpath.
It should be pulled over to gcj at the next import.
I'll look at putting this on the 4.0 branch as well.
