### Question:
JmsDefaultDeserializationPolicy implements JmsDeserializationPolicy { public JmsDefaultDeserializationPolicy() { final String deprecatedAllowList = System.getProperty(DEPRECATED_ALLOWLIST_PROPERTY, CATCH_ALL_WILDCARD); final String allowList = System.getProperty(ALLOWLIST_PROPERTY, deprecatedAllowList); setAllowList(allowList); final String deprecatedDenyList = System.getProperty(DEPRECATED_DENYLIST_PROPERTY); final String denyList = System.getProperty(DENYLIST_PROPERTY, deprecatedDenyList); setDenyList(denyList); } JmsDefaultDeserializationPolicy();  JmsDefaultDeserializationPolicy(JmsDefaultDeserializationPolicy source); @Override JmsDeserializationPolicy copy(); @Override boolean isTrustedType(JmsDestination destination, Class<?> clazz); @Deprecated String getWhiteList(); String getAllowList(); @Deprecated String getBlackList(); String getDenyList(); @Deprecated void setWhiteList(String allowList); void setAllowList(String allowList); @Deprecated void setBlackList(String denyList); void setDenyList(String denyList); @Override int hashCode(); @Override boolean equals(Object obj); static final String CATCH_ALL_WILDCARD; @Deprecated
    static final String DEPRECATED_ALLOWLIST_PROPERTY; @Deprecated
    static final String DEPRECATED_DENYLIST_PROPERTY; static final String ALLOWLIST_PROPERTY; static final String DENYLIST_PROPERTY; }### Answer:
@Test public void testJmsDefaultDeserializationPolicy() { JmsDefaultDeserializationPolicy policy = new JmsDefaultDeserializationPolicy(); assertFalse(policy.getAllowList().isEmpty()); assertTrue(policy.getDenyList().isEmpty()); }
