[jboss-jira] [JBoss JIRA] Commented: (JBAS-1888) Incorrect variable expansion in org.jboss.util.propertyeditor.PropertiesEditor

Eelco de Lang commented on JBAS-1888:
-------------------------------------

My code had the same bug. It can be easily fixed by replacing anything like:

                matcher.appendReplacement(result, replacement);

with:

                // Don't use appendReplacement(result, replacement)!
                // It will remove all slashes.
                matcher.appendReplacement(result, "");
                result.append(replacement);

> When I use the ${jboss.server.data.dir} variable in the example below, it is correctly expanded:
> <attribute name="bla">${jboss.server.data.dir}</attribute>
> However, when I use it in a Properties attribute, the expansion removes backslashes on Windows, e.g. in the example below:
> <attribute name="CacheLoaderConfig">
>     location = ${jboss.server.data.dir}/myCache
> </attribute>
> , I get c:JBoss3.2.7serverdefaultdata/myCache.
> Scott Stark's reply:
> The org.jboss.util.propertyeditor.PropertiesEditor which is what should be used for an attribute of type java.util.Properties does replace ${x} property references in values. The problem is that calling setProperty with the replacement value is not using an escaped string and so the win32 backslash is seen as a char escape sequence. Create a jira issue for this.
