| I tried to use AdoptOpenJDK jdk8u222-b10 instead of Oracle JDK 8. I need to change my JDK, that's not my choice, and I couldn't launch Jenkins because of this issue :

When I rollback to use the Oracle JDK, everything is fine. The problem seems to be the static initialisation bloc inside hudson.util.ChartUtil :
static {
try {
new Font("SansSerif",Font.BOLD,18).toString();
} catch (Throwable t) {
awtProblemCause = t;
awtProblem = true;
}
}
With such code, AWT is referenced even with -Djava.awt.headless=true, because it is static. |
