    [CURATOR-85] curator-client ConnectionState uses deprecated Closeables method - ASF JIRA | 1 year ago
  2. 0

    Tried to upgrade to guava-16 and started getting these errors from Curator on exit: Exception in thread "Thread-1" java.lang.NoSuchMethodError:;)V at org.apache.curator.ConnectionState.close( at org.apache.curator.CuratorZookeeperClient.close( at org.apache.curator.framework.imps.CuratorFrameworkImpl.close( at com.virident.fmc.service.AbstractService.closeCF( at com.virident.fmc.service.AbstractService.shutdown( at com.virident.fmc.service.AbstractService.access$000( at com.virident.fmc.service.AbstractService$ tail: /var/lib/vgccluster/manager.out: file truncated Investigation shows this code: public void close() throws IOException { log.debug("Closing"); Closeables.closeQuietly(ensembleProvider); This closeQuietly() method is deprecated as of guava 14, and it gone in guava 16. The 2-parameter closeQuietly() needs to be called, eg: Closeables.closeQuietly(ensembleProvider, true); Curator master source still seems to have this bug. The 2-parameter closeQuietly is already be available in guava-14 and the 1-parameter version is marked decorated as deprecated in that release which should have generated deprecation warnings. A visual inspection of the various curator projects shows that this deprecated API is used in many places. They all should be corrected to use the 2-parameter Closeables.closeQuietly().
