> Try this in a BeanShell:
> bsh % p = new org.apache.commons.configuration.PropertiesConfiguration();
> bsh % p.setProperty("foo", 6);
> bsh % p.getLong("foo");
> // Error: // Uncaught Exception: Method Invocation p.getLong : at Line: 3 : in file:
<unknown file> : p .getLong ( "foo" )
> Target exception: org.apache.commons.configuration.ConversionException: 'foo' doesn't
map to a Long object
> org.apache.commons.configuration.ConversionException: 'foo' doesn't map to a Long object
>         at org.apache.commons.configuration.AbstractConfiguration.getLong(AbstractConfiguration.java:667)
> The problem is that when an object in a property is not a Long, the only attempt of PropertyConverter.toLong()
is that of treating it as a string. It could try to convert it to a Number first and then
try to convert it to a long. It is a very confusing behaviour, because if you save and reload
the properties everything works fine (as now the integer is a string).
