[jira] [Created] (MCOMPILER-537) Inconsistent behaviour when compiler is forked

Sebb created MCOMPILER-537:
------------------------------

             Summary: Inconsistent behaviour when compiler is forked
                 Key: MCOMPILER-537
                 URL: https://issues.apache.org/jira/browse/MCOMPILER-537
             Project: Maven Compiler Plugin
          Issue Type: Bug
            Reporter: Sebb


Further to MCOMPILER-491, there is another difference between forked and non-forked compiles. Informational messages about deprecation etc are not shown in the forked case.

For example:

$ git clone https://gitbox.apache.org/repos/asf/commons-compress.git --single-branch --branch commons-compress-1.22 --depth 1
$ cd commons-compress
$ mvn clean compile
...
