Building Generated Tests Under JDK 17 Files Due To Modules Export Error

[mrother-stoneriver]

Description

After generating unit tests for existing java classes, the unit tests fail to build to java modules export error.

To Reproduce

Steps to reproduce the behavior:

Have a java class which has a java.util.Date instance variable. Generated test class has the following:

import sun.util.calendar.JulianCalendar;

which when compiles gives the following error

error: package sun.util.calendar is not visible
[ERROR] (package sun.util.calendar is declared in module java.base, which does not export it)

Expected behavior

Generated tests compile.

Actual behavior

Tests failed compilation.

Visual proofs (screenshots, logs, images)

Example:

public void testFail_errors() {
// Couldn't generate some tests. List of errors:
//
// 684 occurrences of:
// Concrete execution failed
}
