InterpolationTest.gltf fails to load, crashes with "Inconsistent animation sampling"

InterpolationTest.gltf has been included in the glTF-Sample-Assets test suite since its inception.
https://github.com/KhronosGroup/glTF-Sample-Assets/tree/main/Models/InterpolationTest

When I try to load it using jme3-plugins, I get warnings followed by a crash:

I discovered issue while testing JME v3.8.0-alpha4. However, the behavior hasn't changed since at least JME v3.2.4-stable, so I don't consider this a regression.

Start by loading Models/InterpolationTest/InterpolationTest.gltf through the jme3-plugins path shown in the report, then read GltfLoader.readAnimation and TrackData.checkTimesConsistency. Use the stack trace to follow how animation sampling is validated. Done means the asset loads without the reported AssetLoadException and the relevant behavior is covered by an appropriate test.
