Second, I see in the Maven repository the 2.3.18 release which seems to be latest, is this the latest formal release (since I see the site mentions 2.3.14)?
Yes, 2.3.18 is the latest, I'll update the webpages.
Thanks.
WBR,
Alexey.

Subject: Re: Adding a filter at runtime
Hi Tiran,
unfortunately in Grizzly 2.3.x FilterChain modification at runtime is tricky (it's fixed on 3.0 branch).
We suggest to install all the Filters in advance and use a switch to turn the filter logic on and off, like here:
https://github.com/AsyncHttpClient/async-http-client/blob/1.9.x/src/main/java/com/ning/http/client/providers/grizzly/GrizzlyAsyncHttpProvider.java#L2446<http://cp.mcafee.com/d/avndzhJ5xddxB55UQsCXCQQmrFIEEFL6QQmrFIELFL6QQmrIEL3DCjqdXCzB5B-Xz9KsEX3BvfDjUwFsPYqvOVJsPYqvOVJ51AQsLmovW_e8FI9IZuVt55C_8ELzC67emKzp5dl55zBgY-F6lK1FJ4SCrLOabUVUQsI3ChNKVIDeqR4IMzapdIxO-252Qb1usRx8-nMDCQbgIn9PCInIvbUjMwvkxyf6zDw_ahJyKOxwzFDsnO4E4s9PCJBzVv2ubhGpAxYqohz8k53OS1acxgkfb252Qb1usRwJ6FCi7NUhQPE61ldxxMSTjUQbRcg-8a8NAa2xVrx7jeY3jqr3bwUS2_id40wwxa14Qgqq87p7P-9EwSpEwyT2sBvdITdYHPcmWyn>
Specifically in your case the problem could be related to FilterChainBuilder instance, which underneath updates existing FilterChain instead of creating a new FilterChain instance.
You can try to create a separate FilterChainBuilder and initiate it with all the Filters you need.
IMO FilterChainBuilder logic (updating an existing FilterChain) is wrong and it has to be fixed. It has to create new FilterChain instance every time build() is invoked. Will appreciate if you can bug an issue for this.
Thank you.
WBR,
Alexey.

Hi all,
I'm trying to add a filter (SSLFilter) at runtime to support a STARTTLS IMAP command.
I tried the following code:
Pair<NIOTransport,FilterChainBuilder> transportData = mTransportsMap.get(aServiceGate.getSecurityLevel());
if (transportData != null)
{
FilterChainBuilder filterChainBuilder = transportData.getSecond();
if (filterChainBuilder != null)
{
// We'll place the SSLFilter right after the TransportFilter
int indexOfTransportFilter = filterChainBuilder.indexOfType(TransportFilter.class);
// Initialize and add SSLFilter
filterChainBuilder.add(indexOfTransportFilter + 1,obtainSSLFilter());
// Secure the entry point connection (build a proper filter chain for this connection)
aEntryPointConnection.setProcessor(filterChainBuilder.build());
}
}
But got the following Exception:
java.lang.ArrayIndexOutOfBoundsException: 6

I came across the following item:
https://java.net/jira/browse/GRIZZLY-1560<http://cp.mcafee.com/d/FZsS93hJ5xddxB55UQsCXCQQmrFIEEFL6QQmrFIELFL6QQmrIEL3DCjqdXCzB5B-Xz9KsEX3BvfDjUwFsPYqvOVJsPYqvOVJ51AQsLmovW_e8FI9IZuVt55C_8ELzC67emKzp5dl55zBgY-F6lK1FJcSCrLOabUVUQsI3ChNKVIDeqR4IMhQPL0T16ktMx6FyDU4wm6wi18l0Vt5ZOVJKDNEnGoxYgkhz8k53OT2eCtU6CQS6n1NI5-Aq81112k29EwQQgeOfDYjh1IPh15K4Va-rpKrWgq0>, which seems to be my problem. I saw that the issue was solved:
1. In which version was it solved (I'm using 2.3.18)?
2. Can someone share a pseudo code (suitable to the 2.3.18 line) of the recommended way to perform a dynamic adding of a filter at runtime?
Thanks,
Tiran Meltser
