Doublekill: SEGFAULT during reporting about SEGFAULT

[vektory79]

Describe the issue
I continue to experiments with PlantUML compilation. Some time ago I report issue #1716, that is not reproduced on GraalVM CE 20.0.0.

But now I meet a wery curiosus error. When plantuml running without parameters it should open Swing window, but SEGFAULT'ed. SVM trying to generate report, but crashed again. Report is uncompleted.

Steps to reproduce the issue

1. git clone https://github.com/vektory79/plantuml-native-image.git
2. cd plantuml-native-image
3. mvn clean compile
4. **zip -d ~/.m2/repository/org/graalvm/nativeimage/svm/20.0.0/svm-20.0.0.jar "com/oracle/svm/core/jdk/Target_java_awt_Toolkit.class" **
5. **zip -d ${JAVA_HOME}/jre/lib/svm/builder/svm.jar "com/oracle/svm/core/jdk/Target_java_awt_Toolkit.class" **
6. mvn package
7. ./target/plantuml
