I am agree, these is a bug, we should not catch an exception which is points on
bug, it should be fixed

Wrapper is internal variable why you initialize it inside? It will be cleaned
after exit from method

sorry these code is illogical.
First of all you are running internalValidateAndSetQuota() before
canDoAction(), so what is idea for using
getReturnValue().getCanDoActionMessages().
Line 572: quotaConsumptionParametersWrapper = new
QuotaConsumptionParametersWrapper(
Line 573: this.getStoragePool(),
this.getReturnValue().getCanDoActionMessages(), this);

Why void and not return, I think to use return is more convenient in java

Line 597: } else {

Line 599: }
Line 600: }
Line 601:
return and not vod
Line 602: private void
addInternalStorageParameters(List<QuotaConsumptionParameter>
consumptionParameters) {
Line 603: List<QuotaStorageConsumptionParameter> storageParameters;
Line 604: storageParameters = ((QuotaStorageDependent)

too many this. We don't use them, so you don't use them also. Or should be used
at very place or nowhere.
Line 606: log.error("Command: " + this.getClass().getName()
Line 607: + ". Quota handling was expected - returned empty
parameters");

Agree, also you don't need implement Serializable, if one of the parents
implements it a son class which is extends it also implements it.

Why parameter performs revert? It is misleading
Line 103: public void revert() {
Line 104: for (QuotaConsumptionParameter parameter :
this.getParameters()) {
Line 105: parameter.revert();
Line 106: }
