VerifyError while creating an AXIS_SWEEP_3 space #2282

Closed stephengold closed 2 weeks ago

stephengold commented 2 weeks ago

In the current "master" branch, creating a PhysicsSpace with the AXIS_SWEEP_3 broadphase option throws a VerifyError. There is no stack trace. Here is typical output:

Here is the test code:

import com.jme3.app.SimpleApplication;
import com.jme3.bullet.PhysicsSpace;

/**

 * @author Stephen Gold sgold@sonic.net
 */
public class TestIssue extends SimpleApplication {

    public static void main(String[] args) {
        TestIssue test = new TestIssue();
        test.start();
    }

    @Override
    public void simpleInitApp() {
        new PhysicsSpace(PhysicsSpace.BroadphaseType.AXIS_SWEEP_3);
    }
}

This issue is a regression, though not a recent one. The test code works fine with JME v3.5.0-alpha1 but not with v3.5.0-beta4 .

That observation led me to suspect the bug was caused by c4b34c8f . Reverting that commit in "master" solves this issue.

I'll investigate what changed between jbullet v1.0.1 and v1.0.2 to cause this issue.
