Null check not backported from openjdk11 to openjdk8 #6

Hi all, I am on a Centos7 machine. and using the following openjdk build. java -version openjdk version "1.8.0_232" OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_232-b09) OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.232-b09, mixed mode)

During execution of our project, we are getting NPE at the following location : net.sf.jasperreports.engine.JRRuntimeException: Error initializing graphic environment. at net.sf.jasperreports.engine.util.JRGraphEnvInitializer.initializeGraphEnv(JRGraphEnvInitializer.java:63) at net.sf.jasperreports.engine.fill.BaseReportFiller.(BaseReportFiller.java:122) at net.sf.jasperreports.engine.fill.JRBaseFiller.(JRBaseFiller.java:236) at net.sf.jasperreports.engine.fill.JRVerticalFiller.(JRVerticalFiller.java:72) at net.sf.jasperreports.engine.fill.JRVerticalFiller.(JRVerticalFiller.java:60)........................... Caused by: java.lang.NullPointerException at sun.awt.FcFontManager.getDefaultPlatformFont(FcFontManager.java:76) at sun.font.SunFontManager$2.run(SunFontManager.java:433) at java.security.AccessController.doPrivileged(Native Method) at sun.font.SunFontManager.(SunFontManager.java:376) at sun.awt.FcFontManager.(FcFontManager.java:35) at sun.awt.X11FontManager.(X11FontManager.java:57) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:442).................

On further investigation, I realized that the missing null check has already been added in openjdk11 but was not backported to previous versions at (FcFontManager.java:76).

Please backport the check to openjdk8 as well as there seems to be no workaround for this exception.

Thanks

@ashishyadav2801 - This should be reported to the jdk8u-dev mailing list at OpenJDK (openjdk.java.net).

Fix is part of https://hg.openjdk.java.net/jdk-updates/jdk11u/rev/008f416a79cba9ec51b476b5761fc8ee564c13f8 which could be backported to 8u.
