Java: FileOutputStream("NUL:") not working in 8u331

ADDITIONAL SYSTEM INFORMATION :
Windows Server 2019
Oracle Java 8u331 (worked in 8u321)

A DESCRIPTION OF THE PROBLEM :
On Windows, NUL is the null output device similar to /dev/null on Linux.

With Oracle Java 8 Update 331, trying to get a new FileOutputStream("NUL:") throws an exception. Previously (Java 8u321) it worked fine.

The problem seems to be the colon:
* new FileOutputStream("NUL") - OK
* new FileOutputStream("NUL:") - exception


REGRESSION : Last worked in version 8

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
try
{
  new FileOutputStream("NUL:");
  System.out.println("OK");
}
catch (FileNotFoundException e)
{
  System.out.println(e);
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
"OK" output
ACTUAL -
java.io.FileNotFoundException: Invalid file path

FREQUENCY : always
