ByteBuffer considered not existing in JDK 22

[Martin Pernollet]

Hi,

Two additional useful information

- this happens with macOS JDK only (tried ARM but not x86). No problem with Windows and Linux
- I get the problem both from Eclipse and when building from command line with Maven :

java.lang.Error:
Unresolved compilation problems:
The type java.nio.ByteBuffer cannot be resolved. It is indirectly referenced from required type org.jzy3d.painters.IPainter
The import java.nio.ByteBuffer cannot be resolved
The type PanamaGLPainter must implement the inherited abstract method IPainter.drawImage(ByteBuffer, int, int, Coord2d, Coord3d)
ByteBuffer cannot be resolved to a type
at org.jzy3d.painters.PanamaGLPainter.<init>(PanamaGLPainter.java:1)
