+Subject: Fix detection of bootjdk on configure
+Upstream: No
+Author: Simon Frankenberger <simon-alpine@fraho.eu>
+
+The alpine builders print out a warning about sched_getaffinity() not working.
+This causes the version check for the boot jdk to fail.
+Patch the command to determine the version number to ignore any errors and warnings.
