Cedomir Igaly commented on CONFIGURATION-808:
---------------------------------------------
Unfortunately, build will never successfully end since master branch can not be
built under JDK 16+
> DefaultListDelimiterHandler.escapeList working only for List<String>
> --------------------------------------------------------------------
>
> Key: CONFIGURATION-808
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-808
> Project: Commons Configuration
> Issue Type: Bug
> Reporter: Cedomir Igaly
> Priority: Minor
>
> When DefaultListDelimiterHandler.escapeList is invoked with list of anything
> except String, it is throwing exception:
> java.lang.ArrayStoreException: java.lang.Integer at
> org.apache.commons.configuration2.convert.DefaultListDelimiterHandler.escapeList(DefaultListDelimiterHandler.java:110)
>
> Reason: {color:#000000}escapedValues{color} is created as String array, but
> assigned to Object array
>
> {color:#0033b3}final {color}{color:#000000}Object{color}[]
> {color:#000000}escapedValues {color}= {color:#0033b3}new
> {color}String[values.size()];
>
> later Object returned from escape is attempted to store into (String) array:
> {color:#000000}escapedValues{color}[idx++] = escape({color:#000000}v{color},
> transformer);
>
> Suggested solution is to create escapedValues as Object array:
> {color:#0033b3}final {color}{color:#000000}Object{color}[]
> {color:#000000}escapedValues {color}= {color:#0033b3}new
> {color}Object[values.size()];
