58-bug-plugin-fails-to-load-after-upgrading-to-193-on-velocity (#60)

* Moving to previous H2 version that was in 1.9.2 that somehow got downgraded

* Reverting back to Java 8 compile target

* removing minimize on shade for Common

* Clearly something here changed something, cause reverting it this way seems to have fixed it

* Cleaning up code here

-   * ParametricNullness parametric nullness}. If a type parameter instead ranges over only non-null
-   * types (or if the type is a non-variable type, like {@code String}), then code should almost
-   * never use this method, preferring instead to call {@code requireNonNull} so as to benefit from
-   * its runtime check.
-   *
-   * <p>An example use case for this method is in implementing an {@code Iterator<T>} whose {@code
-   * next} field is lazily initialized. The type of that field would be {@code @Nullable T}, and the
-   * code would be responsible for populating a "real" {@code T} (which might still be the value
-   * {@code null}!) before returning it to callers. Depending on how the code is structured, a
-   * nullness analysis might not understand that the field has been populated. To avoid that problem
-   * without having to add {@code @SuppressWarnings}, the code can call this method.
-   *
-   * <p>Why <i>not</i> just add {@code SuppressWarnings}? The problem is that this method is
-   * typically useful for {@code return} statements. That leaves the code with two options: Either
-   * add the suppression to the whole method (which turns off checking for a large section of code),
-   * or extract a variable, and put the suppression on that. However, a local variable typically
-   * doesn't work: Because nullness analyses typically infer the nullness of local variables,
-   * there's no way to assign a {@code @Nullable T} to a field {@code T foo;} and instruct the
-   * analysis that that means "plain {@code T}" rather than the inferred type {@code @Nullable T}.
-   * (Even if supported added {@code @NonNull}, that would not help, since the problem case
-   * addressed by this method is the case in which {@code T} has parametric nullness -- and thus its
-   * value may be legitimately {@code null}.)
