OpenJDK 8 (Java 8) on Ubuntu 18 Pros and Cons

Included lambda expressions and date/time API is the best part of jdk 8 Review collected by and hosted on G2.com.

It can make code to run slower if we cannot ise it properly. Review collected by and hosted on G2.com.

Overall openJDK8 is very stable with minor issues.

It is faster, with good amount of new features ( though with Java11 and above , we get even more of them).

And with Ubuntu (or any other Debian distribution) , Java 8 (or any other java version for that matter) , easy of installaion and configuration along with faster application deployments are some major advantage. Review collected by and hosted on G2.com.

Faced some issues with java thread pool management (with jboss) when upgarding to openJDK8.

There were some config changes done which weren't properly documented that caused performance issues with our application. Review collected by and hosted on G2.com.

OpenJDK 8 on Ubuntu 18 provides access to a wide range of development tools and libraries available in the Java ecosystem. This includes various IDEs like Eclipse and IntelliJ IDEA, build tools like Apache Maven and Gradle, and numerous Java libraries and frameworks.

By combining the advantages of OpenJDK 8 as a robust Java implementation and the stability and usability of Ubuntu 18 as an operating system, it can create a reliable and efficient environment for Java development and deployment, which also helps our customers and us.

No anything has come across which makes me dislike it so far. Its really a good and robust combination. Review collected by and hosted on G2.com.

Open source platform for java in Ubuntu, new API for date time manipulation. It is very supportive of the java developer systems, function programming, and new javascript version. Review collected by and hosted on G2.com.

Good for small java projects, it is supportive, but for large java projects, its sdk version didn't support it. Review collected by and hosted on G2.com.

I like every part of Java Development Kits, they are so eloquent, efficient and so fun to learn in the first place and one can solve any business problem at hand with ease. Review collected by and hosted on G2.com.

Of course, it is less featured as compared to the latest JDKs but I did not really dislike anything, Open JDK version 8 is sort of the standard for many software and businesses that implement it, and I feel is the most spread and widely used as of now. It has great community support because of the same fact. Review collected by and hosted on G2.com.

It is free and quite popular in the open source community which makes its user base quite huge. Hence, community support is really great. All this makes it the default choice for new java programmers. Review collected by and hosted on G2.com.

While it may be good for a simple java project or library, the performance is not as great as other free java distributions like Amazon Corretto. There are significant differences seen in memory management and performance on scale as compared to Corretto, Corretto being on a much better side. Review collected by and hosted on G2.com.

OpenJDK 8 is repackaged so that it leaves an object as logically held within the thread even after the premise releases it. It has a quick optimizing bytecode compiler that is capable of performing various activities such as numbering, inlining, and class analysis. It holds unique heaps of compiled code in its code cache, which are not relocated by its GC. Review collected by and hosted on G2.com.

Concurrency is slightly on the areas of improvements end for OpenJDK 8 as it is essential to handle multiple instruction streams and execute them through logical expressions simultaneously. Apart from this, the remaining features are quite convincing to use. Review collected by and hosted on G2.com.

The two best things about openjdk are the open source nature of the product and the continuous improvements it has seen over the past times. Review collected by and hosted on G2.com.

There are competitors for openjdk who are providing longer support. Review collected by and hosted on G2.com.

There are some points which I like a lot about OpenJDK as below :

1. To download JDK you don't require an Oracle account as it's open-source and free for all.

2. You got more releases or updates of subversion or new versions that will fix bugs or issues as more community support is available as it's under GNU license

3. When using ubuntu and OpenJDK its faster and got more support if you need help regarding some dependencies

4. I used open JDK 11 as well so quite not found many issues in any this is quite good to use. Review collected by and hosted on G2.com.

There are a few issues which I faced and that was the reason which I was quite uncomfortable :

1. Sometimes patch update caused many issues and its hard to manage all other update and things

2. compare with oracle JDK, open JDK has not good garbage collecter

3. Faced many issues related to library/dependencies which is available and working fine with oracle JDK but when using open JDK we required more libraries and dependencies to work with the same for example JACOCO plugins Review collected by and hosted on G2.com.

JavaScript engine by Nashorn.

There are several ways to express lambda.

Runtime access to parameter names.

Annotations about Java types.

Operation of bulk data for Collections.

The Permanent Generation has been removed.

GC Combinations that are rarely used are removed Review collected by and hosted on G2.com.

In terms of privacy and security, Ubuntu is a far superior alternative. Ubuntu's main selling point is its simplicity. Moreover, along with OpenJDK, it extremely improves the developer's efficiency with the cost-effective solution therefore, no dislike can be found yet. Review collected by and hosted on G2.com.
