Theo Harper commented on AMQNET-852:
------------------------------------
Propose fix would be to use:
{code:java}
LastIndexOf(")", StringComparison.Ordinal)
or
LastIndexOf(")", StringComparison.InvariantCulture){code}
> Culture-sensitive LastIndexOf causes ArgumentOutOfRangeException in Session
> constructor when thread culture is non-English (.NET 5+)

> Key: AMQNET-852
> URL: https://issues.apache.org/jira/browse/AMQNET-852
> Project: ActiveMQ .Net
> Issue Type: Bug
> Components: MSMQ
> Affects Versions: API-2.2.0
> Environment: Linux / Thai Locale
> Reporter: Theo Harper
> Priority: Critical
>
> We are seeing unexpected {{System.ArgumentOutOfRangeException}} errors during
> construction of {{Apache.NMS.ActiveMQ.Session}} when running under certain
> non-English cultures. The issue is caused by the use of *culture-sensitive
> string APIs* inside the library, specifically {{LastIndexOf(")")}} on
> {{{}brokerUri.Query{}}}, which returns different results under different
> cultures in .NET 5+ due to ICU globalization changes.
> When the application runs under a non-English culture (e.g., {*}fr-FR{*},
> {*}zh-CN{*}, etc.), the following exception occurs:
> System.ArgumentOutOfRangeException: startIndex cannot be larger than length
> of string. (Parameter 'startIndex')
> This originates from:
> {{brokerUri.Query.LastIndexOf(")")}}
> which returns an unexpected index, causing:
> {color:#000000}Substring(brokerUri.Query.LastIndexOf({color}{color:#000000}")"{color}{color:#000000})
> + {color}{color:#000000}1{color}{color:#000000}){color}
> to attempt to start beyond the string boundary.
> Under {*}en-US culture{*}, no exception occurs.
