Sam Brannen 380184e85a Support SpEL compilation of #root or #this with non-public type Prior to this commit, if a Spring Expression Language (SpEL) expression referenced the root context object via the #root or #this variable, we inserted a checkcast in the generated byte code that cast the object to its concrete type. However if the root context object's type was non-public, that resulted in an IllegalAccessError when the compiled byte code was executed. VariableReference.getValueInternal() already contains a solution for global variables which inserts a checkcast to Object in the generated byte code instead of to the object's concrete non-public type. This commit therefore applies the same logic to #root (or #this when used to reference the root context object) that is already applied to global variables. Closes gh-32356	2 years ago

Sam Brannen 380184e85a Support SpEL compilation of #root or #this with non-public type

Prior to this commit, if a Spring Expression Language (SpEL) expression
referenced the root context object via the #root or #this variable, we
inserted a checkcast in the generated byte code that cast the object to
its concrete type. However if the root context object's type was
non-public, that resulted in an IllegalAccessError when the compiled
byte code was executed.

VariableReference.getValueInternal() already contains a solution for
global variables which inserts a checkcast to Object in the generated
byte code instead of to the object's concrete non-public type.

This commit therefore applies the same logic to #root (or #this when
used to reference the root context object) that is already applied to
global variables.
