RestStore parallel iteration fails for non-string keys if UTF-8 is not the default charset ------------------------------------------------------------------------------------------ Key: ISPN-4551 URL: https://issues.jboss.org/browse/ISPN-4551 Project: Infinispan Issue Type: Bug Security Level: Public(Everyone can see) Components: Remote Protocols, Server Affects Versions: 7.0.0.Alpha5 Reporter: Ion Savin Assignee: Ion Savin Fix For: 7.0.0.Beta1 On systems where UTF-8 is not the default charset parallel iteration over non-string keys fails. Non-string keys are mapped to strings prefixed by \uFEFF when the entry is stored. The key is URL-encoded and the prefix is stored properly. The GET /cacheName (all keys) response however uses the system-default charset and if that's not UTF-8 the prefix cannot be mapped and ends up being "?". To reproduce set the charset to ISO-8859-1 and run RestStoreParallelIterationTest and you should see failures similar to this one: {noformat} [testng-RestStoreParallelIterationTest] Test testSequentialIteration(org.infinispan.persistence.rest.RestStoreParallelIterationTest) failed. 10:11:27,629 ERROR [org.infinispan.test.fwk.UnitTestTestNGListener] (testng-RestStoreParallelIterationTest) Test testSequentialIteration(org.infinispan.persistence.rest.RestStoreParallelIterationTest) failed. org.infinispan.persistence.spi.PersistenceException: ISPN022005: Error loading entries from remote server at org.infinispan.persistence.rest.RestStore.process(RestStore.java:295) at org.infinispan.persistence.ParallelIterationTest.runIterationTest(ParallelIterationTest.java:103) at org.infinispan.persistence.ParallelIterationTest.testSequentialIteration(ParallelIterationTest.java:64) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.testng.internal.MethodInvocationHelper.invokeMethod(MethodInvocationHelper.java:84) at org.testng.internal.Invoker.invokeMethod(Invoker.java:714) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:901) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1231) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:127) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:111) at org.testng.TestRunner.privateRun(TestRunner.java:767) at org.testng.TestRunner.run(TestRunner.java:617) at org.testng.SuiteRunner.runTest(SuiteRunner.java:348) at org.testng.SuiteRunner.access$000(SuiteRunner.java:38) at org.testng.SuiteRunner$SuiteWorker.run(SuiteRunner.java:382) at org.testng.internal.thread.ThreadUtil$2.call(ThreadUtil.java:64) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) Caused by: org.infinispan.persistence.spi.PersistenceException: Execution exception! at org.infinispan.persistence.rest.RestStore.process(RestStore.java:292) ... 22 more Caused by: java.util.concurrent.ExecutionException: java.lang.NullPointerException at java.util.concurrent.FutureTask.report(FutureTask.java:122) at java.util.concurrent.FutureTask.get(FutureTask.java:188) at org.infinispan.executors.ExecutorAllCompletionService.pollUntilEmpty(ExecutorAllCompletionService.java:48) at org.infinispan.executors.ExecutorAllCompletionService.submit(ExecutorAllCompletionService.java:32) at org.infinispan.persistence.rest.RestStore.submitProcessTask(RestStore.java:304) at org.infinispan.persistence.rest.RestStore.process(RestStore.java:284) ... 22 more Caused by: java.lang.NullPointerException at org.infinispan.persistence.ParallelIterationTest$2.processEntry(ParallelIterationTest.java:106) at org.infinispan.persistence.rest.RestStore$1.call(RestStore.java:314) at org.infinispan.persistence.rest.RestStore$1.call(RestStore.java:304) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at org.infinispan.util.concurrent.WithinThreadExecutor.execute(WithinThreadExecutor.java:22) at java.util.concurrent.ExecutorCompletionService.submit(ExecutorCompletionService.java:181) at org.infinispan.executors.ExecutorAllCompletionService.submit(ExecutorAllCompletionService.java:31) ... 24 more {noformat}
