-These `java` options have been removed in JDK @@VERSION_SPECIFICATION@@ and using them results in an error of:
-
->   `Unrecognized VM option` *option-name*
-
-`-XX:InitialRAMFraction=`*ratio*
-:   Sets the initial amount of memory that the JVM may use for the Java heap
-    before applying ergonomics heuristics as a ratio of the maximum amount
-    determined as described in the `-XX:MaxRAM` option. The default value is
-    64.
-
-    Use the option `-XX:InitialRAMPercentage` instead.
-
-`-XX:MaxRAMFraction=`*ratio*
-:   Sets the maximum amount of memory that the JVM may use for the Java heap
-    before applying ergonomics heuristics as a fraction of the maximum amount
-    determined as described in the `-XX:MaxRAM` option. The default value is 4.
-
-    Specifying this option disables automatic use of compressed oops if
-    the combined result of this and other options influencing the maximum amount
-    of memory is larger than the range of memory addressable by compressed oops.
-    See `-XX:UseCompressedOops` for further information about compressed oops.
-
-    Use the option `-XX:MaxRAMPercentage` instead.
-
-`-XX:MinRAMFraction=`*ratio*
-:   Sets the maximum amount of memory that the JVM may use for the Java heap
-    before applying ergonomics heuristics as a fraction of the maximum amount
-    determined as described in the `-XX:MaxRAM` option for small heaps. A small
-    heap is a heap of approximately 125 MB. The default value is 2.
-
-    Use the option `-XX:MinRAMPercentage` instead.
-
-`-XX:+ScavengeBeforeFullGC`
-:   Enables GC of the young generation before each full GC. This option is
-    enabled by default. It is recommended that you *don't* disable it, because
-    scavenging the young generation before a full GC can reduce the number of
-    objects reachable from the old generation space into the young generation
-    space. To disable GC of the young generation before each full GC, specify
-    the option `-XX:-ScavengeBeforeFullGC`.
-
-`-Xfuture`
-:   Enables strict class-file format checks that enforce close conformance to
-    the class-file format specification. Developers should use this flag when
-    developing new code. Stricter checks may become the default in future
-    releases.
-
-    Use the option `-Xverify:all` instead.
