jni version out of date

[Gibbz]

Describe the bug current version jni = "0.21.1" in the library its jni = "0.19.0" this is causing incompatability issues in my app.

Expected behavior working with the latest version

error[E0308]: mismatched types

If i change the version of jni in my cargo down to the same version, i get 19 new other errors... But ive managed to downgrade the version for now and its fixed the error.

Yeah we've got #281 and #376 related to this, but it's gonna be a lot of work that I haven't had time for.
