Thanks very much for this missing API; indeed we need this given we have `isSynthetic` and `isEnumConstant`. That said, I recommend the following changes to fulfill the API standards: (Also note strict fields does not exist in the JLS)


Suggestion:

    /**
     * Returns {@code true} if this field is a strictly
     * initialized field; returns {@code false} otherwise.
     *
     * @return true if and only if this field is a strictly
     * initialized field as defined by the Java Virtual Machine Specification
     * @jvms strict-fields-4.5 Field access and property flags
     * @since Valhalla
     */
    @PreviewFeature(feature = PreviewFeature.Feature.STRICT_FIELDS, reflective = true)
    public boolean isStrictInit() {


Also need to import

import jdk.internal.javac.PreviewFeature;

in the import section.
