[9] RFR (S): 8148753: Compilation fails due to field accesses on array types

[Zoltán Majó]

Hi,


please review the patch for 8148753.

https://bugs.openjdk.java.net/browse/JDK-8148753

Problem: Compiling methods that access fields of array types fails. The 
problem is that both compilers assume that only fields of instance types 
(but not field of array types) can be accessed. However, an array can be 
also seen as an instance type, as every array is a subclass of 
java.lang.Object.

Solution: Treat accesses to fields of array types as accesses to fields 
of java.lang.Object. By convention, the java.lang.Object does not have 
any fields. As a result, the generated code will throw a 
java.lang.NoSuchFieldError exception (the expected behavior in this case).

Testing:
- JPRT;
- all JTREG hotspot/compiler tests on all supported platforms.

Thank you and best regards,


Zoltan
