## Removed Java Options
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.
