Resolution: Resolved
> Add OpenJDK-OpenJ9 travis builds
> --------------------------------
>
> Key: SHIRO-771
> URL: https://issues.apache.org/jira/browse/SHIRO-771
> Project: Shiro
> Issue Type: Improvement
> Components: Documentation
> Reporter: Benjamin Marwell
> Assignee: Benjamin Marwell
> Priority: Major
> Fix For: 2.0.0
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> Different JDKs behave differently.
> There are two major VM implementations, hotspot and OpenJ9 with a very
> different memory layout and garbage collection.
> Hotspot is widely known and one distribution (Oracle OpenJDK) is the JDK used
> in jenkins. However, there are other hotspot distributors, e.g. AdoptOpenJDK
> Hotspot, Amazon Corretto, Zulu, Graal and liberica (and probably others).
> There are also two main OpenJ9 distributors. IBM J9 (formerly closed source)
> which was open sourced as Eclipse OpenJ9. There is currently one binary
> distributor of the VM, which is AdoptOpenJDK.net again.
> As different distributions and VM implementations may have different
> defaults, Shiro should be tested against multiple of those. For example,
> OpenJ9 will have "better NPEs" enabled by default, while most hotspot
> distributions will not. Also, the IllegalAccess Permissions are stricter.
> The goal is to add additional travis jobs.
