Fuite de mémoire Java lors de la vérification de l'espace vide dans le tableau

Oh cher Ramasseur d'ordures. J'ai couru sur une erreur java outOfMemory.

La fonction qui est la source de cette erreur outOfMemory est la suivante:

private static int getNextEmptyId()
{
    int temp = 0;
    for(; temp < blocksList.length; temp++)
    {
        if(blocksList[temp] == null)
        {
           break;
        }
    }
    return temp;
}

BlocksList est un tableau partiellement rempli de la taille de 4096. La fonction est censée vérifier que la première place de la liste est vide (null) afin qu'elle puisse transmettre cet id à la super fonction qui donne l'id au classe de base qui utilise cet id pour créer l'objet et l'ajoute à la liste de blocs.

La fonction getNextEmptyId () est appelée ici:

public class ModBlock extends Block
{

...

    public ModBlock(String name, Material material)
    {
        super(getNextEmptyId(), material);
        GameRegistry.registerBlock(this, name);
        this.setTextureName("terracraft/" + name);
        this.setUnlocalizedName(name);
        this.stepSound = soundStoneFootstep;
    }

}

Qui appelle à nouveau cette fonction via super:

public Block(int par1, Material par2Material)
{
    this.stepSound = soundPowderFootstep;
    this.blockParticleGravity = 1.0F;
    this.slipperiness = 0.6F;

    if (blocksList[par1] != null)
    {
        throw new IllegalArgumentException("Slot " + par1 + " is already occupied by " + blocksList[par1] + " when adding " + this);
    }
    else
    {
        this.blockMaterial = par2Material;
        blocksList[par1] = this;
        this.blockID = par1;
        this.setBlockBounds(0.0F, 0.0F, 0.0F, 1.0F, 1.0F, 1.0F);
        opaqueCubeLookup[par1] = this.isOpaqueCube();
        lightOpacity[par1] = this.isOpaqueCube() ? 255 : 0;
        canBlockGrass[par1] = !par2Material.getCanBlockGrass();
    }
}

Dans AABBPool ligne 50:

44    public AxisAlignedBB getAABB(double par1, double par3, double par5, double par7, double par9, double par11)
45    {
46        AxisAlignedBB axisalignedbb;
47
48        if (this.nextPoolIndex >= this.listAABB.size())
49        {
50            axisalignedbb = new AxisAlignedBB(par1, par3, par5, par7, par9, par11);
51           this.listAABB.add(axisalignedbb);
52        }
53        else
54        {
55            axisalignedbb = (AxisAlignedBB)this.listAABB.get(this.nextPoolIndex);
56            axisalignedbb.setBounds(par1, par3, par5, par7, par9, par11);
57        }
58
59        ++this.nextPoolIndex;
60        return axisalignedbb;
61    }

Dans la ligne de bloc 602:

600    public AxisAlignedBB getCollisionBoundingBoxFromPool(World par1World, int par2, int par3, int par4)
601    {
602        return AxisAlignedBB.getAABBPool().getAABB((double)par2 + this.minX, (double)par3 + this.minY, (double)par4 + this.minZ, (double)par2 + this.maxX, (double)par3 + this.maxY, (double)par4 + this.maxZ);
603    }
