OutOfMemoryError in CPathfindingProcessor with pathing grid 1440x1440

[tdauth]

I have modified the code with some logging:

	public CPathfindingProcessor(final PathingGrid pathingGrid, final CWorldCollision worldCollision) {
		this.pathingGrid = pathingGrid;
		this.worldCollision = worldCollision;
		this.nodes = new Node[pathingGrid.getHeight()][pathingGrid.getWidth()];
		this.cornerNodes = new Node[pathingGrid.getHeight() + 1][pathingGrid.getWidth() + 1];
		System.err.println("Nodes length " + this.nodes.length);
		for (int i = 0; i < this.nodes.length; i++) {
			System.err.println("Inner Nodes length " +  this.nodes[i].length);
			for (int j = 0; j < this.nodes[i].length; j++) {
				this.nodes[i][j] = new Node(new Point2D.Float(pathingGrid.getWorldX(j), pathingGrid.getWorldY(i))); // <--- OutOfMemoryError
			}
		}
		for (int i = 0; i < this.cornerNodes.length; i++) {
			for (int j = 0; j < this.cornerNodes[i].length; j++) {
				this.cornerNodes[i][j] = new Node(
						new Point2D.Float(pathingGrid.getWorldXFromCorner(j), pathingGrid.getWorldYFromCorner(i))); // <--- OutOfMemoryError
			}
		}
		this.pathingGridCellCount = pathingGrid.getWidth() * pathingGrid.getHeight();
	}

I started my map WoW Reforged 4.6 and got the OutOfMemoryError. Both lengths are 1440.
Both the nodes and the cornerNodes would lead to an OutOfMemoryError. Manually changing the size to 5x5 would fix this issue. I have 16 GiBytes RAM but not sure how much Java can use. I start it via command line:

./gradlew :desktop:runGame -Pargs="-loadfile $MAP_DIR -ini $INI_FILE -window"

Increasing the memory does not help:

JAVA_TOOL_OPTIONS="-Xmx4g -Xms1g" ./gradlew :desktop:runGame -Pargs="-loadfile $MAP_DIR -ini $INI_FILE -window"

This is my map https://www.hiveworkshop.com/threads/world-of-warcraft-reforged-4-6.355942/
Dimensions 354x354 (360x360)

Increasing the heap memory for IDEA, using a smaller map and this helped me:

task runGame(dependsOn: classes, type: JavaExec) {
    mainClass = project.mainClassName
    classpath = sourceSets.main.runtimeClasspath
    standardInput = System.in
    workingDir = project.assetsDir
    ignoreExitValue = true
    args cmdargs.split()

    jvmArgs = ["-Xmx8g"]
}

However, the whole thing could be optimized in code.
