1. Whether or not it's safe to update the system wide JDK to 1.9 (aka Java 9) for oXygen 19.1. Oxygen 19.1 does not support Java 9 and will not start with it. So, considering you removed the JRE bundled with Oxygen and it is now using

Hello, First, I'd like to point out that we do not recommend using a system wide Java for Oxygen. Any system wide Java update could potentially affect the app to the point that it may not start. The reason we provide a bundled Java runtime in our Oxygen distribution is that we thoroughly test Oxygen against that specific version of Java and we make sure that it provides the best user experience at the time the product is released. If there is a specific issue with the version of Java runtime bundled with Oxygen that has been fixed in later versions, we provide instructions for replacing the bundled Java runtime with a newer version. the system wide JRE (or JDK), the answer is no, it's not safe to update that to Java 9.

2. Has oXygenXML Editor 19.1 been tested with JDK/JRE 1.9? We have tested v19.1 and know it does not start with it. Java 9 makes some significant changes to the Java architecture and bundled libraries which breaks the Oxygen startup and several features during runtime.

3. If so, are there any known issues affecting oXygen with JDK 1.9? For v19.1 and older, it simply won't start.

4. If so, would it be best to stick with JDK 1.8 for the moment? For Oxygen 19.1 and older, there is no other option right now. Please stick with Java 8.

Solution: Do not use a system wide Java with Oxygen. If you want to run Oxygen with the latest version of Java that is supported, replace the JRE bundled with Oxygen with the latest version of Java 8 available from Oracle: 1. Download the JRE .tar.gz distribution, e.g. jre-8u162-macosx-x64.tar.gz 2. Unpack it, rename its folder to 'jre.bundle' and move it to Oxygen/.install4j (after the old 'jre.bundle' has been removed or renamed). 3. Start Oxygen and check the Java version in Help > About, "System Properties" tab. Look for the "java.runtime.version" property.

Hello,

So apparently Oracle are planning to EOL JDK 1.8 in September this year. In addition to this, I tend to nuke the builtin version of Java bundles within oXygen in .install4j/jre.bundle and replace it with a symlink of .install4j/jre.bundle pointing to the system wide install at /Library/Java/JavaVirtualMachines/current (which is itself a symlink pointing to the current version.

So currently the oXygen installation contains this:

bash-4.4$ ls -l /usr/local/oXygenXML/stable/oxygen/.install4j/jre.bundle lrwxr-xr-x 1 ben wheel 41 20 Dec 08:16 /usr/local/oXygenXML/stable/oxygen/.install4j/jre.bundle -> /Library/Java/JavaVirtualMachines/current bash-4.4$ ls -l /Library/Java/JavaVirtualMachines/current lrwxr-xr-x 1 root wheel 50 1 Nov 03:18 /Library/Java/JavaVirtualMachines/current -> /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk bash-4.4$

What I need to know is:

1. Whether or not it's safe to update the system wide JDK to 1.9 (aka Java 9) for oXygen 19.1. 2. Has oXygenXML Editor 19.1 been tested with JDK/JRE 1.9? 3. If so, are there any known issues affecting oXygen with JDK 1.9? 4. If so, would it be best to stick with JDK 1.8 for the moment?

Copying the user list in because I'm reasonably sure others may be interested in the answers to this one.
