Failure to start with systemstats error message in system.log

[prestonmcgowan]

My older rest-client UI alerted me to an update.
After I installed the update, I receive the following in the system.log when I try to start the application.
systemstats[85]: assertion failed: 17G65: systemstats + 914800 [D1E75C38-62CE-3D77-9ED3-5F6D38EF0676]: 0x40
The rest-client immediately stops.

Version Info:

• rest-client: 3.7.0
• Java: Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
• macOS High Sierra 10.13.6

Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)

rest-client versions tested:

• 3.6 - works
• 3.6.1 - works
• 3.6.2 - systemstats error
• 3.7.0 - systemstats error

Thanks for the detailed note. I'll make it compatible with Java 8 this weekend. It should ideally solve the problem.

(cross posting from #77 )

I've modified the code and dependencies to support Java 8. A build of this version is available here:

• http://download.wiztools.org/rest-client/restclient-ui-fat-3.7.1-SNAPSHOT.jar
• http://download.wiztools.org/rest-client/restclient-ui-3.7.1-SNAPSHOT.dmg

Can the audience test the builds and let me know if it works as expected? Especially in Mac I want help knowing if the .dmg version works with both Java 8 (with no Java 10 installed in parallel) and Java 10.

Once this sanity confirmation is given by the community, I'll publish the release.

RESTClient 3.7.1 released with support for Java 8.

Thanks. I have tested basic functionality on my system.
