Subject [jira] [Created] (CONFIGURATION-605) XMLConfiguration drops configuration key immediately following one whose value contains a comma
Date Mon, 20 Jul 2015 13:03:05 GMT
Emil Lundberg created CONFIGURATION-605:
-------------------------------------------

             Summary: XMLConfiguration drops configuration key immediately following one whose
value contains a comma
                 Key: CONFIGURATION-605
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-605
             Project: Commons Configuration
          Issue Type: Bug
          Components: Format
    Affects Versions: 1.9, 1.8, 1.7, 1.6, 1.5, 1.4, 1.3, 1.10
         Environment: $ uname -a
Linux <hostname> 4.1.2-2-ARCH #1 SMP PREEMPT Wed Jul 15 08:30:32 UTC 2015 x86_64 GNU/Linux

$ java -version
openjdk version "1.8.0_45"
OpenJDK Runtime Environment (build 1.8.0_45-b14)
OpenJDK 64-Bit Server VM (build 25.45-b02, mixed mode)
            Reporter: Emil Lundberg
            Priority: Minor


The following XML document:

    StringBuilder sb = new StringBuilder("<configuration>");
    sb.append("<test1>a,b,c</test1>");
    sb.append("<test2>a</test2>");
    sb.append("<test3></test3>");
    sb.append("<test4>a,b\\,b,c</test4>");
    sb.append("</configuration>");

when passed into [`XMLConfiguration#load(Reader)`][commons-doc-xml] and then to [`ConfigurationUtils#toString`][commons-doc-utils],
comes out like this:

    test1=[a, b, c]
    test3=
    test4=[a, b,b, c]

I'm assuming this is a bug.

I've found two workarounds to this:

 1. Inserting any character between the `test1` and `test2` tags, i.e. `<test1>a,b,c</test1>
<test2>a</test2>`
 2. Calling `setDelimiterParsingDisabled(true)` on the XMLConfiguration before loading the
document

For reproduction with a minimal example, see [this GitHub repo][github]. I also posted this
as [a question on Stack Overflow][stack-overflow] before posting here.
