ColdFusion 11 and Java 8u25 and -XX:+UseStringDeduplication don't want to work

Question

I have a ColdFusion 11 update 2 server and I wanted to try out new Java UseStringDeDuplication

Setting that does work

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005 -XX:+UseG1GC 
-Xbatch -Dcoldfusion.home={application.home} -Duser.language=en 
-Dcoldfusion.rootDir={application.home} -Dcoldfusion.libPath={application.home}/lib 
-Dorg.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true
-Dcoldfusion.jsafe.defaultalgo=FIPS186Random

Setting that does not work

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005 -XX:+UseG1GC
-XX:+UseStringDeduplication 
-Xbatch -Dcoldfusion.home={application.home} -Duser.language=en
-Dcoldfusion.rootDir={application.home} -Dcoldfusion.libPath={application.home}/lib 
-Dorg.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true
-Dcoldfusion.jsafe.defaultalgo=FIPS186Random

I am wondering if some additional settings need to be changed

Answer 1

What is the underlying issue you are trying to solve. I would bet (as you can see) that ColdFusion doesn't support this as there are secondary effects with (probably) date time parsing.

Answer 2

This error is just an additional logging with no behavioural impact. This stack trace is not showing the exact message, if ColdFusion is not starting. To identify the exact error message, try the following:-

1. Stop ColdFusion service, if already running.
2. Launch Command prompt as Administrator.
3. Browse to cf_root\cfusion\bin and run the following command coldfusion -start console.
4. Try to access the ColdFusion Admin, once the services are started.

In case it gives an error message, please share the same.
