@mk124, found an issue with passing arrays to java function - it is impossible to pass other values except for an array and size of the array to java function. Server is being crashed.
Java code:

PHP код:

        instance.registerFunction("java_TestArray", objects -> {
            int someValue = (Integer) objects[0]; // in this line the java.lang.ClassCastException is being thrown (read below)
            Integer[] array = (Integer[])objects[1];
            for (int i = 0; i < array.length; i++) {
                if(someValue == 33) {
                    array[i] = (i + 2) * 4;
                } else {
                    array[i] = i+1;
                }
            }
            return 1;
        }, Integer.class, Integer[].class, Integer.class); 


The next message follows after calling the java function from pawn:

Pawn code (I'm not sure that the problem is in here):

PHP код:

    new array[32];
    CallShoebillFunction("java_TestArray", 33, array, sizeof(array));
    for(new i = 0; i < 32; i++) {
        printf("array[%d] = %d", i, array[i]);
    } 


Also, I tried to move first parameter to the last, and it's worked, but after execution of java function I get NullPointerException message:
Java code:

PHP код:

        instance.registerFunction("java_TestArray", objects -> {
            int someValue = (Integer) objects[2];
            Integer[] array = (Integer[])objects[0];
            for (int i = 0; i < array.length; i++) {
                if(someValue == 33) {
                    array[i] = (i + 2) * 4;
                } else {
                    array[i] = i+1;
                }
            }
            return 1;
        }, Integer[].class, Integer.class, Integer.class); 


Pawn code (remains the same, just moved 33 to the end):

PHP код:

    new array[32];
    CallShoebillFunction("java_TestArray", array, sizeof(array), 33);
    for(new i = 0; i < 32; i++) {
        printf("array[%d] = %d", i, array[i]);
    }
    return 1;

[20:06:02][ERROR][err] java.lang.NullPointerException

Or maybe I did something wrong when passing any value to the java function?
