Looks like all of the fastdebuginfo.zip bundles are also missing from this build.

$ ls /java/re/jdk/1.8.0/promoted/all/b73/bundles/*/*debuginfo-[0-3]*.zip | grep -v '^l' | wc -l
      51

$ ls /java/re/jdk/1.8.0/promoted/all/b73/bundles/*/*fastdebuginfo-[0-3]*.zip | grep -v '^l' | wc -l
      17

$ ls /java/re/jdk/1.8.0/promoted/all/b74/bundles/*/*debuginfo-[0-3]*.zip | grep -v '^l' | wc -l
      34

$ ls /java/re/jdk/1.8.0/promoted/all/b74/bundles/*/*fastdebuginfo-[0-3]*.zip | grep -v '^l' | wc -l
/java/re/jdk/1.8.0/promoted/all/b74/bundles/*/*fastdebuginfo-[0-3]*.zip: No such file or directory
       0

Also, we went from 51 "debuginfo.zip" bundles in JDK8-B73 down to
34 "debuginfo.zip" bundles in JDK8-B74. I haven't figured out which
ones are gone...
