Exception on render thread: "NGTriangleMesh: buildGeometry failed"

[GUEVEL, Emanuel]

Hello,

I am using JavaFX 8 for a 3D visualization application.
I display a set of TriangleMesh and under some circumstances, an exception is thrown on the JavaFX rendering thread ("QuantumRenderer") in NGTriangleMesh.validate().
The message is "NGTriangleMesh: buildGeometry failed".

I know this exception is thrown when the mesh geometry data are incorrect, but in this case the behavior is inconsistent : the same data may or may not be considered invalid.
It seems the problem occurs more often when more memory is allocated to the JVM (via -Xms and -Xms command arguments).

I use JDK8u92 32 bits on Windows.

Does anyone encounter the same problem ?
Do you have a solution ?

Thanks in advance.

Best regards,
Emanuel
