Subject: set default compatible cds alignment to auto for arm64
X-Git-Tag: archive/raspbian/21.0.7_8ea-1+rpi1^2~5
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=bc909b6873037567d6b5d9f560aa813208c9363e;p=openjdk-21.git

set default compatible cds alignment to auto for arm64

Bug: https://bugs.openjdk.org/browse/JDK-8334895
Last-Update: 2024-06-25

ARM64 requires cds alignment option to be enabled if CDS is enabled.
Setting it to true will enable the option even if CDS is disabled
causing a configuration error. Setting option to auto allows one to
enable it only when CDS is enabled.
