Tellier Benoit updated JAMES-2278:
----------------------------------
Description:
As reported by lmilev on the gitter chat, passing known sequence sets to
QRESYNC leads to an error in the IMAP layer:
{code:java}
INFO | jvm 1 | 2018/01/03 12:25:15 | [imapserver-executor-17] ERROR
org.apache.james.imap.processor.base.AbstractChainedProcessor - Error while
processing IMAP request

{code}
I tried to write a MPT test but it is not trivial as it depends on random
values (UIDVALIDITY) and non fixed values (MODSEQ). Moreover the code is messy,
dirty and not explicit.
The incriminated lines seems to be:
{code:java}
if (knownUidsList.size() > index++) {
int msnAsInt = msn.intValue();
MessageUid knownUid = knownUidsList.get(index);
// Complicated sequential stuff
}
{code}
As this little test shows it:
{code:java}
@Test
public void test() {
int i = 0;
System.out.println(i++);
System.out.println(i++);
}
// Will output
// 0
// 1
{code}
The index can clearly be out of range.
{code:java}
if (knownUidsList.size() > ++index) {
int msnAsInt = msn.intValue();
MessageUid knownUid = knownUidsList.get(index);
// Complicated sequential stuff
}
{code}
Should fix the issue.
We should find a way to provide *at least* unit tests for that issue.
