autoconf/bootcycle-spec.gmk.template-47-# Any CDS settings generated for the bootjdk are invalid in the bootcycle build.
autoconf/bootcycle-spec.gmk.template-48-# By filtering out those JVM args, the bootcycle JVM will use its default
autoconf/bootcycle-spec.gmk.template-49-# settings for CDS.
autoconf/bootcycle-spec.gmk.template:50:JAVA_FLAGS := $(filter-out -XX:SharedArchiveFile% -Xshare%, $(JAVA_FLAGS))
