IllegalArgumentException thrown from ErrorGeneratingFilter
----------------------------------------------------------
Key: DIRMINA-739
URL: https://issues.apache.org/jira/browse/DIRMINA-739
Project: MINA
Issue Type: Bug
Components: Filter
Affects Versions: 2.0.0-M6
Reporter: Stephen Crane
I've configured an ErrorGeneratingFilter in my tests and am now occasionally
seeing the following exception:
{code}
Caused by: java.lang.IllegalArgumentException: n must be positive
at java.util.Random.nextInt(Random.java:250)
at
org.apache.mina.filter.errorgenerating.ErrorGeneratingFilter.manipulateIoBuffer(ErrorGeneratingFilter.java:187)

org.apache.mina.filter.errorgenerating.ErrorGeneratingFilter.messageReceived(ErrorGeneratingFilter.java:118)
at
org.apache.mina.core.filterchain.DefaultIoFilterChain.callNextMessageReceived(DefaultIoFilterChain.java:433)
{code}
Obviously buffer.remaining() is returning 0 here.
How about the following fix?
{code}
if (buffer.remaining() > 0 && changeByteProbability > rng.nextInt(1000)) {
// as before
}
{code}
