This bug originated from the following question raised by Fujitsu engineers:

==== Fujitsu Question Start ===
When we investigate the src fix diff. for 4745575,
we find out the portion which seems to cause resource leak.

In src/windows/native/sun/windows/ShellFolder.cpp(1.4.2_11),

The current line#702 - 706 is
------->
// Get the screen DC
HDC dc = GetDC(NULL);
if (dc == NULL) {
return NULL;
}
<------
However, if dc==NULL, resource leak seems to occur.

We think that portion should be as follows.
------>
// Get the screen DC
HDC dc = GetDC(NULL);
if (dc == NULL) {
+ ::DeleteObject(iconInfo.hbmColor);
+ ::DeleteObject(iconInfo.hbmMask);
return NULL;
}
<-----
