             Summary: Utility method to convert configuration value to map
                 Key: SLING-2625
                 URL: https://issues.apache.org/jira/browse/SLING-2625
             Project: Sling
          Issue Type: Improvement
          Components: Commons
            Reporter: Chetan Mehrotra
            Priority: Minor


As per current form support for capturing configuration values its not possible 
to capture key=value pairs. To enable capturing of such pairs through 
configuration admin ui one has to use an array property consisting of key=value 
pairs

@Property(value = {
   "poolSize=5",
   "timeout=50",
})
private static final String DATASOURCE_PROPS = "options";

It would be helpful to have a method in 
org.apache.sling.commons.osgi.PropertiesUtil.toMap(Object value,String[] 
defaultValue). Which can parse such config and converts it to a map. Attached 
patch provides such an implementation which does the conversion using following 
rules

1. Entries are of the form key=value
2. Key is trimmed
3. Value is trimmed. If a trimmed value results in an empty string it is 
treated as null
4. Malformed entries like 'foo','foo=' are ignored
5. Map entries maintain the input order i.k linkedhashmap
