JSRSubroutineInfo (Jikes RVM API)

```
final class JSRSubroutineInfo
extends Object
```
This class is used during the building of reference/non-reference maps for a method. Once a JSR/RET combination has been processed, other JSR may be encountered that "jump" to the same subroutine. To calculate the maps of the instruction that is immediately after the JSR, we need the maps at the time of the JSR and the maps at the time of the RET.
