Use correct length when obtaining the ocid buffer (java-native-access…

…#723)

Motivation:

We need to use the correct calculated length when obtaining the ocid
buffer as otherwise it might fail when operating on a slice

Modifications:

- Use the calculated length

Result:

Don't fail when operating on slices
