> Applications that use JNI or FFM need to use the `--enable-native-access` flag, or include the Enable-Native-Access attribute in their JAR files. Currently, the CDS archive cannot use optimized module handling when `--enable-native-access` is specified, so such applications do not support CDS.
>
> This patch no longer disables optimized module graph so long as the `--enable-native-access` is consistent between dump time and runtime. The modules list provided by the option is stored in the RO region of the CDS archive. Verified with tier 1-5 tests and a new regression test.
