The Java software platform provides a number of features designed for improving the security of Java applications. This includes enforcing runtime constraints through the use of the Java Virtual Machine (JVM), a security manager that sandboxes untrusted code from the rest of the operating system, and a suite of security APIs that Java developers can utilise.
Oracle, the company that develops Java, fixed the vulnerability exploited to install Flashback on February 14, 2012. [8] However, at the time of Flashback's release, Apple maintained the Mac OS X version of Java and did not release an update containing the fix until April 3, 2012, [12] after the flaw had already been exploited to install Flashback on 600,000 Macs.

On November 12, 2010, Apple Inc. (just three weeks after deprecating its own Java runtime port [44]) and Oracle Corporation announced the OpenJDK project for Mac OS X. Apple will contribute most of the key components, tools and technology required for a Java SE 7 implementation on Mac OS X, including a 32-bit and 64-bit HotSpot-based Java ...
MRJ v2.2.5 was compatible with Sun's Java Development Kit version 1.1.8. [1] Since the transition to Mac OS X, Apple has discontinued MRJ and instead maintains and distributes a port of Oracle's HotSpot Java virtual machine. [2] As of Java 7, Apple has discontinued its own JRE, and Java support on OS X/macOS now comes directly from Oracle.
macOS malware includes viruses, trojan horses, worms and other types of malware that affect macOS, Apple's current operating system for Macintosh computers. macOS (previously Mac OS X and OS X) is said to rarely suffer malware or virus attacks, [1] and has been considered less vulnerable than Windows. [2]
Because Java is a type-safe language, JX can provide isolation between running applications without needing to use hardware memory protection. This technique, known as language-based protection means that system calls and inter-process communication in JX does not cause an address space switch, an operation which is slow on most computers.

A sandbox is implemented by executing the software in a restricted operating system environment, thus controlling the resources (e.g. file descriptors, memory, file system space, etc.) that a process may use. [4] Examples of sandbox implementations include the following: Linux application sandboxing, built on Seccomp, cgroups and Linux namespaces.
