[jira] [Closed] (MCOMPILER-260) Incorrect behavior when multiple number 's have the same value

["Robert Scholte (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/MCOMPILER-260?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Scholte closed MCOMPILER-260.
------------------------------------
       Resolution: Fixed
    Fix Version/s: 3.6

I could reproduce it with previous versions of the maven-compiler-plugin, but not with the current SNAPSHOT. Could very well be fixed as part of the required change for MCOMPILER-279
Added IT with [r1763652|http://svn.apache.org/viewvc?rev=1763652&view=rev] to prevent regression.

>             Project: Maven Compiler Plugin

>    Affects Versions: 3.3
>         Environment: JDK 1.8.0_45
> Maven 3.3.1

> The following configuration:
> {code:xml}
> <compilerArgs>
>     <arg>-Xmaxwarns</arg>
>     <arg>7</arg>
>     <arg>-Xmaxerrs</arg>
>     <arg>7</arg>
> </compilerArgs>
> {code}
> always fails, because the last 7 is not passed to javac. However, changing any of the numbers so that they're not equal, makes it succeed. Another case where it may succeed, is when an additional argument is appended. For example the following succeeds:
> {code:xml}
> <compilerArgs>
>     <arg>-Xmaxwarns</arg>
>     <arg>7</arg>
>     <arg>-Xmaxerrs</arg>
>     <arg>7</arg>
>     <arg>-Werror</arg>
> </compilerArgs>
> {code}
> However, this is not always the case. For example, the following fails:
> {code:xml}
> <compilerArgs>
>     <arg>-Xmaxwarns</arg>
>     <arg>7</arg>
>     <arg>-source</arg>
>     <arg>7</arg>
>     <arg>-Werror</arg>
> </compilerArgs>
> {code}
> Also note that the numbers do not necessarily have to be adjacent, e.g. the following fails as well:
> {code:xml}
> <compilerArgs>
>     <arg>-Xmaxwarns</arg>
>     <arg>7</arg>
>     <arg>-source</arg>
>     <arg>1.5</arg>
>     <arg>-Xmaxerrs</arg>
>     <arg>7</arg>
> </compilerArgs>
> {code}
