Hi Sergei,
In Ubuntu, we've applied a patch to erlang to specify the java bytecode
compatibility level to use when building. This patch was first applied
during the transition to openjdk6, so it's quite old, and currently we only
support openjdk8 in testing/unstable/the Ubuntu devel series so there is
*currently* no effect on compatibility to not use this patch. However,
there will be future java transitions again, so in discussion with the
Ubuntu Java maintainers we've agreed it's useful to keep this patch instead
of dropping it.
So as the same logic seems to apply to Debian, I am forwarding the patch for
your consideration.
Thanks,

+Description: Build backwards compatible bytecode.
+ By default, javac compiles bytecode which is compatible
+ with the Java implementation the JDK originates from and
+ onwards.
+ .
+ This patch ensures that bytecode is compatible with Java
+ 1.8 and up.

Sorry, I've just noticed that you've solved this problem separately in
Debian by encoding JAVA_OPTIONS in debian/rules. So please disregard this
bug report.
