Prebuilt Valhalla JDK build 26-jep401ea2

[Cay Horstmann]

Thanks, it worked with that branch.

Here the GC.class_histogram outputs.

Without --enable-preview:

    1:      50000003     1200000072  java.time.LocalDate (java.base at 26-jep401ea2)
    2:             1      200000016  [Ljava.time.LocalDate; (java.base at 26-jep401ea2)
  
With --enable-preview:

    1:             1      400000016  [Ljava.time.LocalDate; (java.base at 26-jep401ea2)

Cheers,

Cay

> Hi, how was that build created? When I build from scratch from https://github.com/openjdk/valhalla <https://github.com/openjdk/valhalla>, I get a different behavior with the last example on https://inside.java/2025/10/27/try-jep-401-value-classes/ <https://inside.java/2025/10/27/try-jep-401-value-classes/> (i.e. no heap flattening).
