One option:

... // somewhere inside a method...
final ApnsClient apnsClient;
{
  try {
    apnsClient = receiveApnsConnection(...);
  } catch (IllegalArgumentException iae) {
    logger.error(iae.getMessage(), iae);
    senderCallback.onError(String.format("Unable to connect to APNs (%s))", iae.getMessage()));
    return; // adios !
  }
}

versus this one:

... // in some methods....
final ApnsClient apnsClient;
try {
  apnsClient = receiveApnsConnection(...);
} catch (IllegalArgumentException iae) {
  logger.error(iae.getMessage(), iae);
  senderCallback.onError(String.format("Unable to connect to APNs (%s))", iae.getMessage()));
  return; // adios!
}

for some reason I do find the first one a bit more readable, due to the strcuted {} block
