This appears to be due to this JDK issue, which was fixed in JDK 8u25.
And sure enough, here's the JDK version for failing builds:
-- Found Java: /opt/toolchain/sun-jdk-64bit-1.8.0.05/bin/java (found suitable version "1.8.0.05", minimum required is "1.7")
And here it is for successful builds:
19:06:12 -- Found Java: /usr/lib/jvm/java-1.8.0-openjdk-amd64/bin/java (found suitable version "1.8.0.111", minimum required is "1.7")
We either need to blacklist JDK8 versions older than u25, or we need to condition the scalafmt step on the JDK version.
