From Panama 17 to 19, ability to get M1?

[Martin Pernollet]

Hi all,

Just tried to switch to JExtract samples for JDK 19. I am suprised by the fact that the following imports shown in the JExtract Teapot sample (on master banch, hence v19) can't be resolved

import java.lang.foreign.MemorySession;

import java.lang.foreign.SegmentAllocator;

And indeed, as shown by this picture, java.lang has no foreign subfolder in JDK 19

However, I found foreign packages to still appear in jdk.incubator module.

May this be due to me downloading JDK19 from the panama page? https://jdk.java.net/panama/

For strings the type would be a pointer, so the ValueLayout.ADDRESS layout or the C_POINTER layout generated by jextract can be used for instance.
