Error in Spark TypeManager when enabling full Reflective reasoning

[ddevec]

Steps to reproduce: 1.) Hello, I'm attempting to develop a static datarace detection pass using Soot, and Spark but I would like sound analysis (e.g. reasoning conservatively about reflection). I've found Soot crashes when running Spark on a simple program if "types-for-invoke" and safe-newinstance are both enabled.

I've enabled the safe-forename, safe-newinstance, and types-for-invoke options of the cg. However, it appears that this bug occurs with the combination of the safe-newinstance and types-for-invoke flags both enabled.

Files used to reproduce: Test java file contents below:

class Simple1 {
  static int a = 0;

  public static void main(String[] args) {
    Thread t1 = new Thread() {
      public void run() {
        a = 7;
        System.out.println("a is: " + a);
      }   
    };  

    Thread t2 = new Thread() {
      public void run() {
        a = 10; 
        System.out.println("a is: " + a);
      }   
    };  

    t1.start();
    try {
      t1.join();
    } catch (InterruptedException ex) {
      ex.printStackTrace();
    }   

    t2.start();
    try {
      t2.join();
    } catch (InterruptedException ex) {
      ex.printStackTrace();
    }   

    a = 0;
    t1 = new Thread() {
      public void run() {
        a = 2;
        System.out.println("a is: " + a);
      }   
    };  

    t2 = new Thread() {
      public void run() {
        a = 3;
        System.out.println("a is: " + a);
      }   
    };  

    t1.start();
    t2.start();

    try {
      t2.join();
    } catch (InterruptedException ex) {
      ex.printStackTrace();
    }   
    try {
      t1.join();
    } catch (InterruptedException ex) {
      ex.printStackTrace();
    }   
  }
}
