Java 8 gapless time series chart OutOfMemoryError with XYShapeBuilder

Issue

I get an OutOfMemoryError with XYShapeAnnotation and Arrays.copyOf() when running the demo app's gapless-time annotations case with Java 8 on Ubuntu 20.04.5 LTS.

jfreechart-builder/demo-app/src/main/java/com/jfcbuilder/demo/JFreeChartBuilderDemo.java

Line 602 in 48fdcab

private static JFreeChart stockChartDailyNoGapsWithAnnotations() {

This happens if it's compiled with JDK 8 or 11 targetting 8 AND launching it with Java 8. If I launch it with Java 11 the issue doesn't occur. If I comment out the demo app's use of XYShapeBuilder it ceases to occur.

Java 8 Version

$ java -version
openjdk version "1.8.0_352"
OpenJDK Runtime Environment (build 1.8.0_352-8u352-ga-1~20.04-b08)
OpenJDK 64-Bit Server VM (build 25.352-b08, mixed mode)

Steps to Reproduce

sudo apt-get install openjdk-8-jdk
sudo apt-get install openjdk-11-jdk
sudo update-alternatives --config java (select JDK 8)
java -version (confirm Java 8)
cd path/to/jfreechart-builder/repo
mvn clean install
cd path/to/.m2/repository/com/jfcbuilder/jfreechart-builder-demo/VERSION
java -jar jfreechart-builder-demo-VERSION.jar
From the Demonstrations drop-down pick the Gapless | Annotations and Markers one.
Observe the app freezes then shows an eventual out of memory exception.
Use the alternatives to switch to Java 11
Launch the JAR again and pick the same annotations demo.
Observe the app doesn't freeze and doesn't throw the exception.

I didn't test this on Windows.

Some hypotheses on why it's happening:

XYShapeBuilder doesn't map x-coordinates to time array indices, possibly leaving shape coordinates out of view, then with Java 8 that creates a problem?
Based on the exception stack trace there's a logic issue in the JDK 8 implementation where an array being copied is huge, or there is an issue with indexing?

The workarounds are:

If running with Java 8 don't use XYShapeBuilder
Use a later version of Java.
