i think i’ve found a bug in kotlin converter,
Java Code

Collection<Long> values = fetchList();
            Long[] valuesAsArray = new Long[values.size()];
            values.toArray(valuesAsArray);

Kotlin conversion

val values = fetchList()
            val valuesAsArray = arrayOfNulls<Long>(values.size)
            values.toTypedArray()

and all elements in valuesAsArray will be null

I think there's no bug. Typed arrays of non primitives have null values by default in java

[nerses]

the bug is that valuesAsArray in java had the data

[nerses]

in kotlin it contains just nulls

Java Code and Kotlin Code are different, aren’t they?

[nerses]

yes and that’s the problem. i have converted using intellij java to kotlin converter

In third line

Ah.. So you mean Idea conversion tool..

[nerses]

kotlin code should be

val values = fetchList()
val valuesAsArray = values.toTypedArray()

[nerses]

yes
