Description

When trying to load a file (Ternary.java) where the following nested ternary expression is used within JML, KeY opens a window titled "Parser Error" with the message "null at .../Ternary.java:2:30 Caused by: java.lang.NullPointerException" and marks true as the problem:

//@ ensures \result == (((true ? (0 + 1) : 2) > 3) ? 4 : 5);
int foo() {
    return (((true ? (0 + 1) : 2) > 3) ? 4 : 5);
}

However, this should be valid Java Syntax – when replacing
//@ ensures \result == (((true ? (0 + 1) : 2) > 3) ? 4 : 5);
with
//@ ensures \result == 5; in Ternary.java so that now only the Java Code contains the same ternary expression, the file becomes loadable and foo provable.

Note: The problem seems to occur only with this specific nesting of ternary operators and a simple expression. It does NOT occur e.g. when omitting 0 + , when using only one ternary operator or when putting the second ternary operator in place of the 4 (resulting in ((6 > 3) ? (true ? (0 + 1) : 2) : 5)) or the 5.

Reproducible

always

Steps to reproduce

  1. load Ternary.java in KeY
  2. experience a Parser Error
  3. replace the nested ternary in JML with 5
  4. load Ternary.java again
  5. note that the file is now loadable and provable

The file should be loadable and foo provable with the use of the nested ternary operator in JML – 2. should not occur.

File: Ternary.java.zip

Additional information

The "Parser Error" window contains the message

The following exception occured:

null at xxx/Ternary.java:2:30

Caused by: java.lang.NullPointerException

"Show Details" gives the following stacktrace:

There definitely should not be an NPE. However, the type of the two arguments is different. One is \bigint the other one is int. This is how KeY got confused.

fixes #3149 (#3150)

Ternary operators would not have a type unless the arguments have
identical types. This fix takes the promoted common type as result type.
This works in particular if \bigint and int are combined.
