Description
When converting an existing code base I found that else-if apparently is not supported. Here's an example:
public static void main(String[] args) {
int a = 0;
if (a == 1) {
System.out.println("a=1");
} else if (a == 2) {
System.out.println("a=2");
}
}which fails with the output
$ j2py HelloWorld.java
Traceback (most recent call last):

nextNode = nextNode.children[2]
With the obvious workaround of separating the if statements, the conversion is successful:
public static void main(String[] args) {
int a = 0;
if (a == 1) {
System.out.println("a=1");
}
if (a == 2) {
System.out.println("a=2");
}
}converts to
