[Native Image] `ArrayIndexOutOfBoundsException` with `-H:AdvancedObfuscation`

[sgammon]

Describe the Issue

When using -H:AdvancedObfuscation with an app that uses Truffle Enterprise, a crash occurs

Using the latest version of GraalVM can resolve many issues.

• I tried with the latest version of GraalVM.
