Description

tests.api.java.io.FileTest@test_mkdir failes on win XP:

mkdir 257 failed
junit.framework.AssertionFailedError: mkdir 257 failed at tests.api.java.io.FileTest.test_mkdir(FileTest.java:1811) at java.lang.reflect.VMReflection.invokeMethod(Native Method)

To get more information run stand alone test:

import java.io.*;
public class Test2 {
public static void main(String[] args) throws IOException {
// Test for method boolean java.io.File.mkdir()
String base = System.getProperty("user.dir");
int dirNumber = 1;
boolean dirExists = true;
File dir = new File(base, String.valueOf(dirNumber));
while (dirExists) {
if (dir.exists())

{ dirNumber++; dir = new File(base, String.valueOf(dirNumber)); }

else

{ dirExists = false; }

}
if (!dir.mkdir() && dir.exists()) System.out.println("mkdir failed");
else System.out.println("PASSED_1");

dir.deleteOnExit();

StringBuilder sb = new StringBuilder(dir + File.separator);
while (dir.getCanonicalPath().length() < 256)

{ sb.append(0); dir = new File(sb.toString()); if (!dir.mkdir() && dir.exists()) System.out.println("mkdir " + dir.getCanonicalPath().length() + " failed"); else System.out.println("PASSED_2"); dir.deleteOnExit(); }

}
}

The debug shows the problem is in nt_exception_filter.cpp

While iterative run of luni module with -Dhy.test.forkmode=perTest tests.api.java.io.FileTest@test_mkdir fails 50 times out of 50.
The stand alone code fails from time to time on win XP
