Using jdk 20, i see the selected thread is changing without user interaction.
I have not seen such behavior on other JDKs yet.

  1. sampling eclipse IDE running on a jdk 20 JDK,

  2. while sampling select Thread "Java indexing" - "Show Only this Thread"
    image
    =>
    image

  3. then in eclipse hit "rebuild index"
    image

=> after some time the selected Thread switches to "JNA Cleaner"
image

Expected behavior
Selected Thread does not switch
