| 44 | * These two arrays are used to validate the line number |
| 45 | * information returned by JDI. There are limitations to |
| 46 | * this approach: |
| 47 | * - there are no strict rules about |
| 48 | * what constitutes the "right" line number mapping, so |
| 49 | * this kind of test may have false negatives with other |
| 50 | * compilers. |
| 51 | * - this test is also sensitive to the compiler's code generation; |
| 52 | * if that changes, this test will likely need updating. |
| 53 | * - this test assumes that JDI code index == class file |
| 54 | * byte code index which may not be true in all VMs. |
| 55 | * - To find the values for these tables, compile ControlFlow.java and then |
| 56 | * do: |
| 57 | * javap -classpath _jj1.solaris-sparc/JTwork/classes/com/sun/jdi \ |
| 58 | * -l ControlFlow |
