Crash when compiling Antlr in the QualitasCorpus

[Sebastian Hjelm]

ExtendJ 8.0.1-220-gfec29ac Java SE 8

When compiling the Antlr project from the QualitasCorpus ExtendJ crashes with a NullpointerException. The stacktrace is attached in the issue.

I compiled using: java -Xss1024m -Xms4096m -jar extendj.jar @systems_10\antlr-4.0

Here is a small test case that provokes the same crash:

public class Er1 {
  public static void main(String[] args) {
    assertEqulas(10, ident("bar"));
  }

  static <U, V> V ident(U t) {
    return t;
  }
}

Fix out of bounds parameter indexing issues

When accessing a method or constructor parameter type, the parameter index was in some cases out of bounds of the actual parameter list. This has been fixed by introducing a helper attribute to safely compute the type of a parameter.
