VerifyError for compiled SpEL expression with primitive/reference type mix when using == [SPR-12557]

[spring-projects-issues]

Andy Clement opened SPR-12557 and commented

When the operands to an == call are not numbers the method .equals() is used to compare them. If, in this situation, one of the operands is actually a primitive type then we need to box that primitive before calling equals. Currently this box operation is missing from the generated code, leading to a verify error. For example: ```
new String(35) == 35

Fixed (to include the boxing byte code) with tests.
