NullComparisonTestBean.java.txt

Affects: 4.3.16
When evaluating an expresion involving a numeric comparison with a boxed integer, it fails when using the bytecode compiled expression.

Very similar to #SPR-16489. Can be reproduced using the attached test case.

The problem, apparently, resides in method Operator.generateComparisonCode(). Its generated code does append bytecodes for unboxing values when necessary, but doesn't take into account a potential NPE. In interpreted mode, null check is made in method StandardTypeComparator.compare().
