[ Upstream commit 36b8d4628d3cc8f5a748e508cce8673bc00fc63c ]
When a build is run from something like a cron job, the user's $PATH is rather minimal, of note, not including /usr/sbin in my own case. Because of that, an automated rpm package build ultimately fails to find libperf-jvmti.so, because somewhere within the build, this happens...
/bin/sh: alternatives: command not found /bin/sh: alternatives: command not found Makefile.config:849: No openjdk development package found, please install JDK package, e.g. openjdk-8-jdk, java-1.8.0-openjdk-devel
...and while the build continues, libperf-jvmti.so isn't built, and things fall down when rpm tries to find all the %files specified. Exact same system builds everything just fine when the job is launched from a login shell instead of a cron job, since alternatives is in $PATH, so openjdk is actually found.
The test required to get into this section of code actually specifies the full path, as does a block just above it, so let's do that here too.
