 * <p>Note on class-level isolation: Compiled Script classes are cached and reused.
 * Class-level state (static fields, metaclass mutations) persists across evaluations
 * of the same script. In Fess, scripts are short expressions configured by
 * administrators (e.g., "data1 &gt; 10", "10 * boost1 + boost2") and do not use
 * static state, so this is acceptable.</p>
