Sam Starling commented on APLO-6:
---------------------------------

Hi Hiram, thanks for the fix. As I'm not familiar with JVM, can you give an example of how
this option is set please?

> When using a character other than a period as a topic separator (.), Apollo throws the
following exception:
> {code} 
> org.apache.activemq.apollo.util.path.PathParser$PathException: Invalid destination path
part: 'event/abc', it does not match regex: [a-zA-Z0-9\_\-\%\~]+
> {code}
> In the example, we're using {{/topic/event/abc}} as a topic. In {{[PathParser.java|http://svn.apache.org/viewvc/activemq/activemq-apollo/trunk/apollo-util/src/main/scala/org/apache/activemq/apollo/util/path/PathParser.java?view=markup]}},
line 47 determines that {{path_seperator = new AsciiBuffer(".")}}. Thus, Apollo incorrectly
tokenizes the topic and so {{event/abc}} fails the regular expression on line 48 of the same
file.
> In short, it should be possible to specify what the topic separator is, or (even better)
detect when a different character is being used as a delimiter.
