A DESCRIPTION OF THE PROBLEM :
Calling toRGB() on a CIEXYZ ColorSpace leaks Posix semaphores and exhausts system files.

REGRESSION. Last worked in version 6u31

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Put the following code in a file named Test.java:

    import java.awt.color.ColorSpace;
    public class Test
    {
        public static void main(String[] args) throws Throwable {
            final ColorSpace CIEXYZ = ColorSpace.getInstance(ColorSpace.CS_CIEXYZ);
            for(int i = 0; i < 100000; i++) {
                CIEXYZ.toRGB(new float[] {80f, 100, 100});
            }
            new java.io.FileInputStream("Test.java").close();
        }
    }

Run javac Test.java
Run java Test


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The program shouldn't output anthing
ACTUAL -
Exception in thread "main" java.io.FileNotFoundException: Test.java (Too many open files)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:138)
