Description kazuhiro kawana 2021-02-09 09:13:25 UTC
### Description of problem:
We got NullpointerException from java.awt.color.ICC_Profile using openjdk11 and openjdk 1.8.0.

A same issue was reported in JDK bug database and already fixed:

Fixed bug: 
https://bugs.openjdk.java.net/browse/JDK-6986863

Related bug:
https://bugs.openjdk.java.net/browse/JDK-8058973
https://bugs.openjdk.java.net/browse/JDK-8254737

It looks OpenJDK 11(latest) and OpenJDK 1.8.0(latest) does not contain the above fix. Please a backport the fix.

### Version-Release number of selected component (if applicable):
- java-11-openjdk-11.0.10.0.9-4.el8_3.x86_64
- java-1.8.0-openjdk-1.8.0.282.b08-2.el8_3.x86_64

### How reproducible:

Anytime

### Steps to Reproduce:
1: Install latest openjdk 11 or openjdk 1.8.0: 

I installed openjdk 11 or openjdk 1.8.0.

2: Comple sample code "MTInitCMM.java"

===
# cat MTInitCMM.java
import java.awt.color.ColorSpace;
import java.awt.color.ICC_Profile;
import java.awt.color.ICC_ProfileRGB;
import java.util.concurrent.CountDownLatch;

public final class MTInitCMM {

    public static void main(String[] args) throws Exception {
        ICC_ProfileRGB rgb = (ICC_ProfileRGB) ICC_Profile.getInstance(ColorSpace.CS_sRGB);
        Thread[] threads = new Thread[100];
        CountDownLatch go = new CountDownLatch(1);
        for (int i = 0; i < threads.length; i++) {
            threads[i] = new Thread(() -> {
                try {
                    go.await();
                } catch (InterruptedException e) {
                    throw new RuntimeException(e);
                }
                rgb.getMatrix();
            });
        }
        for (Thread thread : threads) {
            thread.start();
        }
        go.countDown();
        for (Thread thread : threads) {
            thread.join();
        }
    }
}
