FULL PRODUCT VERSION :
1.8.0_b123

ADDITIONAL OS VERSION INFORMATION :
Windows 7 x64

A DESCRIPTION OF THE PROBLEM :
The change

http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/ac22a52a732c

causes a regression.

The parameter "append" in the constructor

public FileHandler(String pattern, int limit, int count, boolean append)

doesn't work anymore. Every time, a java program a new File is generated (when using %u in Filename), instead of appending to the existing one.

REGRESSION. Last worked in version 7u60

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
package javaapplication23;

import java.io.IOException;
import java.util.logging.FileHandler;

public class JavaApplication23 {

public static void main(String[] args) throws IOException {
new FileHandler("./test_%g_%u.log", 10000, 100, true);
}

}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Only the file test_0_0.log (and .lck) should be generated.
ACTUAL -
With every program start, a new file is generated (test_0_1.log, test_0_2.log, ...)

REPRODUCIBILITY :
This bug can be reproduced always.
