jnr-unixsocket v0.23 and above forces osgi.ee;filter:="(&(osgi.e e=JavaSE)(version=9.0))"

[nvatvani]

When using JDK1.8, jnr-unixsocket v0.22 and below correctly sets osgi.ee;filter:="(&(osgi.e e=JavaSE)(version=1.8))" but v0.23 and above forces osgi.ee;filter:="(&(osgi.e e=JavaSE)(version=9.0))".

Given that JDK1.8 is still supported, can jnr-unixsocket v0.25-SNAPSHOT have its dependencies adjusted so that osgi.ee;filter:="(&(osgi.e e=JavaSE)(version=1.8))" persists and one is not forced to upgrade to JDK9?

The dependency involved that forces osgi.ee;filter:="(&(osgi.e e=JavaSE)(version=9.0))" is described here:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=537751

.. specifically "org.objectweb.asm" which is a transitive dependency of jnr-enxio.

It is "org.objectweb.asm" that forces JDK9.

Hmm...so how do I fix this?

You hack it by specifying <_noee>true</_noee> under instruction tag of the maven-bundle-plugin

The _noee tag removes all minimum versioning enforcement of the runtime JRE.

Ok I tried this patch but I did not see any difference in the MANIFEST. I also did not see any Require-Capability in the MANIFEST before I made the change, so I'm confused about how to proceed.
