Some application classes are missing in the generated callgraph

[rahlk]

It turns out that when we build a call-graph when WALA (1.5.9) on various applications, we observe the following problems.

1. All the classes in the application are available in CHA, but there are a number of classes that are not available in the call graph as seen in [§2]().

2. We tried a number of context sensitivity levels, and for each level, we found a number of non-overlapping missing classes. a. Generally, RTA has more classes that 0-CFA and 01-CFA. b. There are some classes in 0-CFA and 01-CFA that are not seen in RTA and vice-versa.

   1. Setup

We looked at 4 applications:

1. Daytrader JavaEE 7
2. Daytrader JavaEE 8
3. Cargotracker JakartaEE
4. Plantsbywebsphere JavaEE 7

We take into account the dependencies that constitute these application.
