Emmanuel Bourg commented on CONFIGURATION-272:
----------------------------------------------
ConfigurationUtils.copy() calls setProperty on the target configuration with
the value returned from getProperty() on the source configuration. The target
configuration performs a new value parsing but it should not. A workaround is
to disable the parsing of the delimiter before copying, and restore it after
the copy :
target.setDelimiterParsingDisabled(true);
ConfigurationUtils.copy(source, target);
target.setDelimiterParsingDisabled(false);
> ConfigurationUtils.copy results in escaped "," characters no longer being
> escaped

> Key: CONFIGURATION-272
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-272
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 1.4
> Environment: commons 1.4
> Reporter: John Meagher
> Fix For: 1.5
>
>
> When using ConfigurationUtils.copy to go between configuration formats any
> escaped out "," characters are put into the output configuration without the
> escape character. This results in a different value being returned from
> getString calls as it now things the property is a list. If 4 escape
> characters are used instead of the expected 1 then the copy will end up with
> the correct value, but then the original will end up with the escape
> character as part of the property value.
> Example:
> SomeLongProperty=This is a test\, it is only a test
> # Ends up right in the copy, but not right in the original
> SomeOtherProperty=This is also a test\\\\, it is also only a test
> After copy:
> # Missing "\" before ","
> SomeLongProperty=This is a test, it is only a test
> SomeOtherProperty=This is also a test\, it is also only a test
