I am using Sikuli-api to automate a standalone application. This application starts on running *.bat file. In code I am opening this application as:

 m_sikscr=new SikuliScript();
    m_sikscr.openApp("path of bat file");

I am getting below exception on this openApp() command.

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x515ee11e, pid=3992, tid=5868
#
# JRE version: Java(TM) SE Runtime Environment (8.0_20-b26) (build 1.8.0_20-b26)
# Java VM: Java HotSpot(TM) Client VM (25.20-b23 mixed mode windows-x86 )

Whereas, when I try to open same bat file via below line of code, it gets open successfully.:

String[] command = {"cmd.exe", "/C", "Start", "*.bat"};
    Runtime r = Runtime.getRuntime();
     Process p = r.exec(command);
     p.waitFor();

Below is stack trace :

I am failing to understand if it is an issue with bat file or Sikuli.

Based on what you show, sikuli calls into native code, where Win32utils fails. This is how Java reports Crashes in C code.

You most likely forgot some configuration bit.

  • I set `JPARAM=-Xms64M -Xmx512M -Dfile.encoding=UTF-8` environment variable, as got some hint from [here](https://answers.launchpad.net/sikuli/+faq/2220). For now , `openApp()` method not crashing the JVM. But I am not sure if JPARAM environment variable did the trick. (not that experienced in Java.) – MKay Oct 01 '15 at 09:36

I got similar issue with openApp() but on OS X. As workaround i use old versiom Sikuli (1.0.1).

  • Thank you for sharing the bug. As I commented on below answer, I set JPARAM env. veriable. Do you think it would have solved the problem? Since JVM is not crashing on openApp method. – MKay Oct 05 '15 at 04:09
