JNA no longer buildable with a target JDK of 1.6

[lwahonen]

Hi,

Commit 267bbce calls the parameterCount method, which has been marked as >= 1.8.

Looks like this is easily patched via m.getParameterTypes().length, but the whole VARIANT is full of magic so I'm afraid of breaking something here.

Cheers,
Will

Good catch - the build produces bytecode that is compatible with a 1.6 VM, but the classpath is more problematic. We can't build against a JDK < 8 because for support for JDK >= 9 we need annotations introduced with JDK 8.

For the concrete problem, I agree with your solution.

@lwahonen could you please have a look at: PR #1026? That PR fixes the incompatibilities and introduces animal-sniffer to prevent regressions. Does that look good to you?

[lwahonen]

Looks great to me! I'm not very familiar with animal-sniffer, but looks like it can't be worse than nothing.

Thanks for checking. I merged the changeset to master and will give it a few days to settle. I want to see if other problems crop up and if not, I'll cut a release from that.
