Some investigation on #374: It seems to me, that this problem isn't related to In all places (e.g., in the child process) where we construct concrete (Any?) values from models, we highly depend on This is the code snippet we use: package org.utbot.common
import org.utbot.common.Reflection.setModifiers
import java.lang.reflect.AccessibleObject
import java.lang.reflect.Field
import java.lang.reflect.Modifier
import sun.misc.Unsafe
object Reflection {
val unsafe: Unsafe
init {
val f: Field = Unsafe::class.java.getDeclaredField("theUnsafe")
f.isAccessible = true
unsafe = f.get(null) as Unsafe
}
private val modifiersField: Field = Field::class.java.getDeclaredField("modifiers") // problem is here
init {
modifiersField.isAccessible = true
}
fun setModifiers(field: Field, modifiers: Int) {
modifiersField.set(field, modifiers)
}
}
inline fun <R> AccessibleObject.withAccessibility(block: () -> R): R {
val prevAccessibility = isAccessible
try {
isAccessible = true
return block()
} finally {
isAccessible = prevAccessibility
}
}The problem is that from Java 12, there is no such field The quick workaround: Method getDeclaredFields0 = Class.class.getDeclaredMethod("getDeclaredFields0", boolean.class);
getDeclaredFields0.setAccessible(true);
Field[] fields = (Field[]) getDeclaredFields0.invoke(Field.class, false);
Field modifiers = null;
for (Field each : fields) {
if ("modifiers".equals(each.getName())) {
modifiers = each;
break;
}
}
assertNotNull(modifiers);and add this to running options: Will try this out |
