 | `$BPL_JFR_ARGS`         | Configure custom arguments to Java Flight Recording, via a comma-separated list, e.g. `duration=10s,maxage=1m`. If any values are specified, no default args are supplied.
+| `$BP_JVM_JLINK_ENABLED`         | Configures whether to run the JDK's jlink tool at build time to generate a custom JRE. Defaults to `false`. If no custom args are specified, the default args are `--no-man-pages --no-header-files --strip-debug --compress=1`.
