"incompatible property" error when using --add-modules, --add-opens, --add-exports, etc.

[Boyce, Jeffrey]

Hello,

I am attempting to evaluate performance improvements afforded by the Leyden CDS enhancements for an embedded application running on aarch64.  The application makes extensive use of the --add-modules, --add-opens, and --add-exports command line arguments.  However, it appears that these arguments are incompatible with the -XX:CacheDataStore option, as their use results in errors similar to the following:

[0.004s][warning][cds] optimized module handling/full module graph: disabled due to incompatible property: jdk.module.addopens=java.base/java.nio=org.apache.tomcat.embed.core
Error occurred during initialization of VM
CacheDataStore cannot be created because AOTClassLinking is enabled but full module graph is disabled

Is this the expected behavior?  If yes, is there a workaround or a plan to support these options in the future?


Thanks,

Jeff Boyce
