jcp removes comments even if /r is not specified

[ndw]

I've been upgrading some code in a project. It had been using jcp 5.3.2 and when I upgraded to 7.0.3, I discovered that comments were being stripped out even though the "r" option was not specified.

I tried a few versions up to 6.1.4 and confirmed that this behavior first appears in 7.0.0.

could you provide example of comments which were removed?
do you use jcp directly or as a plugin for ant/maven/gradle process?

I want to have more than one preprocess step and that doesn't appear (from my position of relative gradle ignorance) to be possible, so I'm just running it directly as a JavaExec step.

I put the attached file (renamed to .txt to make GitHub uploading happy) in /tmp/x/src and run this command:

$ java -jar ~/.gradle/caches/modules-2/files-2.1/com.igormaznitsa/jcp/6.1.4/3cfbec66a0d86bc5b62a8b02e65c6a388c5ed3fc/jcp-6.1.4.jar /c /i:/tmp/x/src /o:/tmp/x/out /p:TEST=false

The resulting file in /tmp/x/out has comments. If I run the same command with version 7:

$ java -jar ~/.gradle/caches/modules-2/files-2.1/com.igormaznitsa/jcp/7.0.3/a23fece25fb6b6764a4e71cdab77b646d73565db/jcp-7.0.3.jar /c /i:/tmp/x/src /o:/tmp/x/out /p:TEST=false

yes, you're right, I will fix

[raydac]

thanks for the report, exactly the keep comments flag in the pre-processor context was false by default
you can try fixed pre-built version
