Source: openjdk-11
Version: 11.0.4+11-1
Severity: normal
OpenJDK captures the build user as the USERNAME variable in the configure
script and uses it in an interval VM version string that appears in libjvm.so:
$ strings /usr/lib/jvm/java-11-openjdk-amd64/lib/server/libjvm.so |grep
buildd
buildd
OpenJDK 64-Bit Server VM (11.0.4+11-post-Debian-1) for linux-amd64 JRE
(11.0.4+11-post-Debian-1), built on Jul 17 2019 00:28:36 by "buildd" with gcc
8.3.0
This prevents the openjdk package from being reproducible.
The attached patch modifies the build script to use a fixed value for
the USERNAME variable.
