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.
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.
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

Java 5 Update 5 (1.5.0_05) is the last release of Java to work on Windows 95 (with Internet Explorer 5.5 installed) and Windows NT 4.0. [36] Java 5 was first available on Apple Mac OS X 10.4 (Tiger) [37] and was the default version of Java installed on Apple Mac OS X 10.5 (Leopard). Public support and security updates for Java 1.5 ended in ...
This is designed to allow safe execution of untrusted code from remote sources, a model used by Java applets, and other secure code downloads. Once bytecode-verified, the downloaded code runs in a restricted " sandbox ", which is designed to protect the user from misbehaving or malicious code.
• Don’t download files from unknown sources, either from your email or the web. • Don’t download attachments (pictures, games, electronic greetings) unless it’s from someone you know. If you think you have a virus, we recommend that you immediately use antivirus software to run a scan.
A later variant targeted a Java vulnerability on Mac OS X. The system was infected after the user was redirected to a compromised bogus site, where JavaScript code caused an applet containing an exploit to load. An executable file was saved on the local machine, which was used to download and run malicious code from a remote location.
