----------------------------------
Summary: 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
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.
