Not working RemoteManager.getBulk() and keySet() in compatibility mode ---------------------------------------------------------------------- Key: ISPN-3436 URL: https://issues.jboss.org/browse/ISPN-3436 Project: Infinispan Issue Type: Bug Components: Remote protocols Affects Versions: 6.0.0.Alpha3 Reporter: Jiří Holuša Assignee: Galder Zamarreño Fix For: 6.0.0.Beta1, 6.0.0.Final When using HotRod client in compatibility mode, when trying to put entries via embedded cache and afterwards call RemoteCache.getBulk() or RemoteCache.keySet(), an exception is thrown. Exception is thrown in all cache modes (LOCAL, REPL, DIST). {code:borderStyle=solid} org.infinispan.client.hotrod.exceptions.HotRodClientException:Request for message id[3] returned server error (status=0x85): java.lang.ClassCastException: java.lang.Integer cannot be cast to [B at org.infinispan.client.hotrod.impl.protocol.Codec10.checkForErrorsInResponseStatus(Codec10.java:143) at org.infinispan.client.hotrod.impl.protocol.Codec10.readHeader(Codec10.java:99) at org.infinispan.client.hotrod.impl.operations.HotRodOperation.readHeaderAndValidate(HotRodOperation.java:56) ... {code} Code that did it: {code:title=EmbeddedHotRodBulkTest.java|borderStyle=solid} public void testEmbeddedPutHotRodGetBulk() { Cache<Integer, Integer> embedded = cacheFactory.getEmbeddedCache(); RemoteCache<Integer, Integer> remote = cacheFactory.getHotRodCache(); populateCacheManager(embedded); Map<Integer, Integer> get = remote.getBulk(); assertEquals(100, get.size()); for(int i = 0; i < 100; i++) { assertTrue(get.containsValue(i)); assertTrue(get.containsKey(i)); } } {code}
