Hi,
... missed some lists in my first post ...
I prepared a fifth webrev for this change. Please review.
It incorporates the changes requested by the CSR reviewers (not to remove docuemtation of '-help' where is was documented before) and the changes proposed by Kumar: http://cr.openjdk.java.net/~goetz/wr17/8189102-helpMessage/webrev.05/
See also the information in the webrev itself, there are also patch files with the incremental builds.
This change contains fixes for some langtool tests. I ran the following test suites on it: hotspot, jdk, langtools, nashorn, jaxp, most of them on all the platforms we build.
Best regards, Goetz.

Hi The tools in jdk should all show the same behavior wrt. help flags. This change normalizes the help flags of a row of the tools in the jdk. Java accepts -?, -h and --help, thus I changed the tools to support these, too. Some tools exited with '1' after displaying the help message, I turned this to '0'. Maybe this is not the right mailing list for this, please advise. Please review this change. I please need a sponsor. http://cr.openjdk.java.net/~goetz/wr17/8189102-helpMessage/webrev.01/ In detail, this fixes the help message of the following tools: jar -? -h --help; added -?. jarsigner -? -h --help; added --help. -help accepted but not documented. javac -? --help; added -?. Removed -help. -h is taken for other purpose javadoc -? -h --help; added -h -?. Removed -help javap -? -h --help; added -h. -help accepted but no more documented. jcmd -? -h --help; added -? --help. -help accepted but no more documented. Changed return value to '0' jdb -? -h --help; added -? -h --help. -help accepted but no more documented. jdeprscan -? -h --help; added -? jinfo -? -h --help; added -? --help. -help accepted but no more documented. jjs -h --help; Replaced -help by --help. Adding more not straight forward. jps -? -h --help; added -? --help. -help accepted but no more documented. jshell -? -h --help; added -? jstat -? -h --help; added -h --help. -help accepted but no more documented. Best regards, Goetz.
