LevelDB crashes JVM when stop() is called concurrently with write() ------------------------------------------------------------------- Key: ISPN-4651 URL: https://issues.jboss.org/browse/ISPN-4651 Project: Infinispan Issue Type: Bug Security Level: Public(Everyone can see) Components: Loaders and Stores Affects Versions: 7.0.0.Beta1 Reporter: Radim Vansa Assignee: Radim Vansa This test reproduces the issue: {code} public void testConcurrentWriteAndRestart() { final int THREADS = 4; final AtomicBoolean run = new AtomicBoolean(true); final CountDownLatch started = new CountDownLatch(THREADS); ExecutorService executor = Executors.newFixedThreadPool(THREADS); for (int i = 0; i < THREADS; ++i) { executor.execute(new Runnable() { @Override public void run() { started.countDown(); int i = 0; while (run.get()) { InternalCacheEntry entry = TestInternalCacheEntryFactory.create("k" + i, "v" + i); MarshalledEntry me = TestingUtil.marshalledEntry(entry, getMarshaller()); cl.write(me); ++i; } } }); } try { started.await(); Thread.sleep(1000); cl.stop(); Thread.sleep(1000); cl.start(); Thread.sleep(1000); } catch (InterruptedException e) { throw new IllegalStateException(e); } finally { run.set(false); executor.shutdown(); } } {code}
