Unannotated collection attributes require a Transient annotation

org.openrewrite.java.migrate.javax.AddTransientAnnotationToCollections

In OpenJPA, attributes that inherit from the java.util.Collection<E> interface are not a default persistent type, so these attributes are not persisted unless they are annotated. EclipseLink has a different default behavior and attempts to persist these attributes to the database. To keep the OpenJPA behavior of ignoring unannotated collection attributes, add the javax.persistence.Transient annotation to these attributes in EclipseLink.

    dependencies {
        rewrite("org.openrewrite.recipe:rewrite-migrate-java:2.13.0")
    }
    rewrite {
        activeRecipe("org.openrewrite.java.migrate.javax.AddTransientAnnotationToCollections")
    }
    afterEvaluate {
        if (repositories.isEmpty()) {
            repositories {
                mavenCentral()
