Download Java 8 Update 291 – Features, Patches & Installation

A few days ago, Oracle released Java 8 Update 291. The new update is said to address vulnerabilities spotted in the previous version of Java. So, if you are running an older version of Java, it’s best to install the update as soon as possible.

Java 8 Update 291 introduced a total of 390 security patches. Also, Oracle has changed the Java Runtime Licensing system. The new license permits you to use Java for free for personal and development use, but other uses authorized under prior Oracle Java licenses may no longer be available.

Java 8 Update 291 Features & Notes

• The new update introduced a new system and security properties to control the reconstruction of remote objects by JDK’s built-in JNDI RMI and LDAP implementation.
• Java 8 Update 291 also got two new HARICA Root CA Certifications. Below are the root certifications that have been added to the cacerts truststore:

haricarootca2015 – DN: CN=Hellenic Academic and Research Institutions RootCA 2015, O=Hellenic Academic and Research Institutions Cert. Authority, L=Athens, C=GR

haricaeccrootca2015 – DN: CN=Hellenic Academic and Research Institutions ECC RootCA 2015, O=Hellenic Academic and Research Institutions Cert. Authority, L=Athens, C=GR

• With Java 8 Update 291, the default java version no longer updates the value of the PATH environment variable incorrectly.
• The new update disables the TLS 1.0 and 1.1 by default. It’s because they are no longer considered secure. The TLS 1.1 and 1.1 have been superseded by more secure TLS 1.2 and 1.3.
• Since TLS 1.0 and TLS 1.1 are no longer secure, they have been disabled by default for Java Plugin Applets and Java Web Start applications.
• The new update ensures less ambiguous processing of ProcessBuilder quotes on Windows. Oracle had properly encoded the double-quotes in the command string passed to Windows CreateProcess for each argument to achieve this feat.

Different Between JRE, JDK, and JVM

We are pretty sure you might have heard of JDK, JRE, and JVM before. However, do you know the difference between them? Most often or not, users were found confused between installing JDK and JRE. So, it’s essential to know the difference between the three before downloading Java 8 Update 291.

1. JVM

Well, JVM or Java Virtual Machine is an engine required to run Java applications on a system. JVM is usually included in the JRE package you download from the official Oracle website. JVM can’t be installed separately. The role of JVM is to convert the Java code into machine language to help your machine understand the language.

2. JRE

If you are not a developer, then you will most probably want to install the JRE or Java Runtime Environment. It’s software that’s installed on your system. With JRE, your computer can run applications developed in Java. JRE also includes a JVM, which is discussed above.

3. JDK

JDK or Java Development Kit is a software package made for developers. This includes both JRE and JVM. It’s mostly used to create Java Applets or applications. If you choose to install Java Development Kit on your system, you don’t need to install Java Runtime Environment separately as it includes both JRE and JVM.
