That's a bug. We have tests that check stop/start/stop procedure:
https://github.com/infinispan/infinispan/blob/master/core/src/test/java/o...
But not tests that check that procedure with the query module in.
Fill it in http://issues.jboss.org/browse/ISPN and we'll sort it out.
Cheers,

This is the code I added:
private static <K, V> Cache<K, V> checkCache(String cacheName) {
final Cache<K, V> cache = cacheManager.getCache(cacheName, false);
if (cache != null) {
final ComponentStatus status = cache.getStatus();
if (status != ComponentStatus.INITIALIZING && status !=
ComponentStatus.RUNNING) {
cache.start();
}
}
return cache;
}
Any other idea?

using it? If it's stopped, you could call cache.start() again.
