corretto/java:8 missing libfreetype.so.6

[Rachit-10]

Describe the bug

The docker image corretto:8-alpine-jdk is being used to build a Maven Application and during the build process I am encountering an error that libfreetype.so.6 is missing. This library is being called by the Apache POI.

To Reproduce

Environment: Alpine / Java 8 / Spring boot 2.1.x
Jib a spring boot 2.1.x app that uses the autoSizeColumn feature of apache-poi and attempt to run the container on your local docker.

OR

Run the following Java Code Snippet:

public class TestApachePOI {
    public static void main(String[] args) {

        XSSFWorkbook xssFWorkbook = new XSSFWorkbook();
        Workbook workBook = new SXSSFWorkbook(xssFWorkbook);
        System.out.println("workBook" + workBook.toString());
    }
}

Following dependencies would be required too:

org.apache.poi:poi-ooxml-schemas:jar:4.1.2:compile
org.apache.poi:poi:jar:5.2.2:compile
org.apache.commons:commons-collections4:jar:4.4:compile
org.apache.commons:commons-math3:jar:3.6.1:compile
com.zaxxer:SparseBitSet:jar:1.2:compile
org.apache.poi:poi-ooxml:jar:5.2.2:compile
org.apache.poi:poi-ooxml-lite:jar:5.2.2:compile
org.apache.commons:commons-compress:jar:1.21:compile
com.github.virtuald:curvesapi:jar:1.07:compile

Hello,
Can you install the Alpine Freetype package with apk add freetype and see if that works for you?

[Rachit-10]

Hi,

Yes I have tried doing that and in that case I am getting java.lang.NullPointerException.

[lutkerd]

Can you share the full NPE when freetype is installed?

[lutkerd]

I created a simple reproducer without the external dependencies and I had to run apk add freetype fontconfig ttf-dejavu to get it working. Without fontconfig and the ttf-devavu fonts I would get an NPE.

import java.awt.Font;
import java.awt.GraphicsEnvironment;

public class FontTest {
    public static void main(String[] args) {
        Font[] fonts = GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();

        for (int i = 0; i < fonts.length; i++) {
          System.out.println(fonts[i]);
        }
    }
}

Exception without Fontconfig and ttf-dejavu:

Yes this patch is working for me now.

Although, I would like to have this library packaged in the standard image provided by the corretto. This is because let's say if I upgrade the image version in the future, i would have to manually make these patches through the Dockerfile.
Also I have a software which I provide to customers and they would also have to do these patches in case of any upgrade.
So I would like to have these libraries be a part of the standard image provided by the corretto itself.
