disk persistence - same conf file, different results

["joao tiago a. m. viegas" <jt...@gmail.com>]

hello,

I've been testing jcs, I want a cache that allows me to save all the
eleemnts when I shutsown gracefully, and later when I create a new instance
of the same cache I can get those same objects I had before in the first
encarnation of that same cache.
I made this test and I'm actually using two identical confs, but for some
reason I'm getting different results.
Could you please help me understanding why?

tests are:

private static final String[] configs = new String[]
> {"ObjectPersistingInMemoryAndDisk_x1.ccf",
> "ObjectPersistingInMemoryAndDisk_x2.ccf"};
>
private static final String[] expecteds = new String[] {null, null};

private static final String region = "OUR_REGION";
> private static final String key="key", value="value";

.....
> .....

@Test
> public void testObjectPersistingInMemoryAndDisk_1() throws Exception{
>
> performObjectPersistingInMemoryAndDisk(JCS_CONFIG_DIR + configs[0],
> expecteds[0]);
> }
>
> @Test
> public void testObjectPersistingInMemoryAndDisk_2() throws Exception{
>
> performObjectPersistingInMemoryAndDisk(JCS_CONFIG_DIR + configs[1],
> expecteds[1]);
> }
>
> private void performObjectPersistingInMemoryAndDisk(String configFile,
> String expected) throws Exception{
>
>
> System.out.println("-----------------------------------------------------------");
>
> System.out.println("testing with config file:" + configFile);
> JCS.setConfigFilename(configFile);
> JCS cache = JCS.getInstance(region);
> cache.put(key, value);
> Thread.sleep(5000);
> Assert.assertNotNull(cache.get(key));
> Assert.assertEquals(value, cache.get(key));
>
> IStats stats = cache.getStatistics().getAuxiliaryCacheStats()[0];
>
> cache.freeMemoryElements(Integer.parseInt(stats.getStatElements()[0].getData()));
> Thread.sleep(5000);
> Assert.assertNotNull(cache.get(key));
> Assert.assertEquals(value, cache.get(key));
> System.out.println(cache.getStats());
> CompositeCacheManager.getInstance().shutDown();
>
> Thread.sleep(5000);
>
> JCS.setConfigFilename(configFile);
> cache = JCS.getInstance(region);
> Assert.assertEquals(expected, cache.get(key));
>
> System.out.println(cache.getStats());
> cache.clear();

> CompositeCacheManager.getInstance().shutDown();
> }
