     *
     * <p>I/O: serializes the AST of each Java type to DiskCache. (This happens even if the
     * compilation unit is later dropped.) If we're using the persistent unit cache, each valid unit
     * will also be serialized to the gwt-unitcache file. (As a result, each AST will be copied
     * there from the DiskCache.) A new persistent unit cache file will be created each time
     * compile() is called (if there's at least one valid unit) and the entire cache will be
     * rewritten to disk every {@link PersistentUnitCache#CACHE_FILE_THRESHOLD} files.
     *
     * <p>This function won't report errors in invalid source files unless suppressErrors is false.
     * Instead, a summary giving the number of invalid files will be logged.
     *
     * <p>If the JDT compiler aborts, logs an error and throws UnableToCompleteException. (This
     * doesn't happen for normal compile errors.)
