Encountering failure in MonoTests.System.Data.SqlClient.SqlParameterTest.Constructor7 on Android with AOT+LLVM enabled

[pjcollins]

The MonoTests.System.Data.SqlClient.SqlParameterTest.Constructor7 test is throwing an NRE when running on recent devices when AOT and LLVM are enabled.

Steps to Reproduce

1. Download prebuilt .apk file, and run it on an armeabi-v8a device:

adb install 15-7-aotllvm-Xamarin.Android.Bcl_Tests-Signed.apk
adb shell am instrument -w Xamarin.Android.Bcl_Tests/xamarin.android.bcltests.NUnitInstrumentation

2. Alternatively, a smaller repro which just contains the relevant test source could likely be built and installed with AOT+LLVM.
