The stack over flow occurs when making many calls to LS2J. The size of the string did not seem to impact the stack, just that it was a string. There seems to be a problem with integers but not as noticible as with strings. I did some testing in 6.5.1 and 6.5.4 with the following results.
| Call Details | | Number of calls
with 6.5.1 & 6.5.4 | |
| One String | | 101,818 | |
| Two Strings | | 50,908 | |
| Three Strings | | 33,938 | |
| One String 10 Integers | | 101,789 | |
| One String 20 Integers | | 101,777 | |
This problem has been “approved for investigation” by IBM. Becuase of this problem I am now forced to convert my document based
LEI LotusScript code to Java. The last count was 4,600 lines of code. The code I used for testing follows.
Java Code
package com.ChadSmiley;
public class StackTest {
public StackTest (){
}
public void String1( String one ){
}
public void String2( String one , String two ){
}
public void String3( String one , String two , String three ){
}
public void String10( String one , String two , String three , String four , String five , String six , String seven , String eight , String nine , String ten ){
}
public void Integer1( int one ){
}
public void Integer2( int one , int two ){
}
public void Integer3( int one , int two , int three ){
}
public void Integer10( int one , int two , int three , int four , int five , int six , int seven , int eight , int nine , int ten ){
}
public void String1Integer10( String sOne, int one , int two , int three , int four , int five , int six , int seven , int eight , int nine , int ten ){
}
public void String1Integer20( String sOne, int one , int two , int three , int four , int five , int six , int seven , int eight , int nine , int ten, int oneone , int onetwo , int onethree , int onefour , int onefive , int onesix , int oneseven , int oneeight , int onenine , int oneten ){
}
