Subject: Misalign address in the test rather than structure
X-Git-Tag: archive/raspbian/17.0.9+9-2+rpi1^2~7
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=390f5f9529f2113627a4c3e7345e1805b086b3b3;p=openjdk-17.git

Misalign address in the test rather than structure

mk68-support.diff aligned metaspace structures by 4 bytes breaking the test.
Add 1 to address type rather than aligned structure to produce misaligned pointer.
