So, the issue seems to actually be with the HashTableSwitchOp that was added in December. The hash function computation seems to yield an incorrect value, leading to an incorrect offset into the jump table. The only explanation I have is that the java version of the hash function doesn't compute the same thing that the binary version computes.

Narrowed it down to compilation of org.graalvm.compiler.java.BytecodeParserOptions_OptionDescriptors.get(Ljava/lang/String;)Lorg/graalvm/compiler/options/OptionDescriptor;
