The lock is read

These method still in use?

Same here lock is read, but you changing a shared state.
Line 733: storagePoolQuotaMap.put(storagePool.getId(), new
HashMap<Guid, Quota>());

parameters.getAuditLogable().getStoragePool();
Line 896: if (storagePool == null) {
Line 897: throw new InvalidQuotaParametersException("Null
storage pool passed to QuotaManager");

Same here, read lock
Line 899: if
(!storagePoolQuotaMap.containsKey(storagePool.getId())) {
Line 900: storagePoolQuotaMap.put(storagePool.getId(), new
HashMap<Guid, Quota>());
Line 901: }

The following exception also is thrown for some down message, ass throws to
method signature. Al least at private methods
Line 904: throw new InvalidQuotaParametersException();
Line 905: }
Line 906: return internalConsumeAndReleaseHandler(parameters,
auditLogPair);
Line 907: }
Line 1118: // if quota was not found in cache - look for it in DB
Line 1119: if (quota == null) {
Line 1120: quota = getQuotaDAO().getById(quotaId);
Line 1121: if (quota != null) {
Line 1122: // cache in quota map
How these can be? That I get from DB a quota which is not related to pool and
why it catch only here?. If method throws exception, throws should be added to
its signature
Line 1123: if (storagePoolId.equals(quota.getStoragePoolId())) {
Line 1124: quotaMap.put(quotaId, quota);
Line 1125: } else {
Line 1126: throw new InvalidQuotaParametersException(
