Hi I have a legacy code in JuMPeR which I’m trying to run with the latest version of JuMP and Julia.  
The command setDefaultOracle is not recognized, and I can not find what it was changed to.  
Does anybody know what it was changed to? did GeneralGraphOracle change as well?

I also tried to run Pkg.test(“JuMPeR”) and got:  
ERROR: LoadError: Some tests did not pass: 1628 passed, 309 failed, 74 errored.  
I can send the full report if anyone is maintaining the package

According to its [REQUIRE](https://github.com/IainNZ/JuMPeR.jl/blob/e161a36abfd541926db9d7591eb6e3ae6ec9bdc4/REQUIRE) file, JuMPeR is compatible with JuMP 0.14 and no later, while the latest version of JuMP is 0.16. So I wouldn’t expect to run JuMPeR with the latest version of JuMP unless you’re willing to or can find someone willing to update it.

Looking at the commit history, @yeesian has recently made updates to JuMPeR, he may provide more information.

In general, you can use the search bar in github to search for the method/function that you’re trying to call to see when it has changed.

I have not tried it myself, but it seems you might just need to [call `setDefaultOracle!` instead of `setDefaultOracle`](https://github.com/IainNZ/JuMPeR.jl/commit/2ac9fabb7cf50d618b4879dbee41e690bdb37fe3).

JuMP actally reverted to the 0.14 version but it still did not work

Thanks for the tip  
I actually tried running the command  
setDefaultOracle!(rm, JuMPeR.GeneralGraphOracle())  
and got the error:  
ERROR: LoadError: UndefVarError: setDefaultOracle! not defined
