* Adjust Record adapter and extend test coverage
* Address review feedback
* Make constructor string more concise
* Add tests for Gson default behavior for static fields
* Improve exception for deserializing static final field
Previously it would report "Unexpected IllegalAccessException occurred..."
due to the uncaught IllegalAccessException.
* Improve handling of exception thrown by accessor
Such an exception is not 'unexpected' (which was claimed by the previous
exception handling) because user code could throw it.
* Improve constructor invocation exception handling and add tests
* Small adjustments to the new record code.
* Replace wildcard imports with single imports.
* Enable `Java17RecordTest` and fix its many previously-hidden problems.
* Use a `Map` to get primitive zero values rather than a potentially-expensive reflective trick.
* Apply some automated code fixes.
* Address review comments.
* Add a currently-failing test for Java records and `@Ignore` it.
Also do the Maven gymastics required to ensure that this test only runs on Java
versions ≥17. (It would also work on Java 16, but 17 is all we have in the CI.)
Fix some compilation problems I saw when running locally, which for some reason
don't show up in the CI.
* Suppress some new lint options that trigger `-Werror`.
We may fix these later. (Every test will need an explicit constructor!)
* Select Java version with maven.compiler.release and maven.compiler.testRelease.
Use `assumeNotNull` rather than an if-statement.
* Specify <release>11</release> for javadoc.
* Restore the @see for AccessibleObject.
