Exception in thread "ajp-bio-8009-exec-1"

Question

I am facing strange error. My all java code runs without any problem on my laptop (windows 7) but when I upload it to our server (linux) then am seeing following in tomcat log:

Exception in thread "ajp-bio-8009-exec-1" java.lang.StackOverflowError

Here is my ErrorCheck.errorMsg code:

public String errorMsg(String subject, Exception e){    
        String stackTrace = "";                 
        try{
            StringWriter sw = new StringWriter();  
                    PrintWriter pw = new PrintWriter(sw);  
                        e.printStackTrace(pw);
                            stackTrace = sw.toString();          
                        stackTrace = stackTrace.replaceAll("\n","<br>");                        SendEmail.send("[email protected]","[email protected]",subject,stackTrace);         
                pw.close();
                pw = null;      
            sw.close();
            sw = null;

            System.gc();

        }catch(Exception ex){
        ex.printStackTrace();
        }           
    return stackTrace;
    }

Please advise.

Thanks in anticipation

Answer 1

The actual problem was as following:

I was writing in my code:

ErrorCheck ec = new ErrorCheck();
String error = ec.error();

and then was calling in catch block

ec.errorMsg(error+"SendEmail.send()", e);

I removed from all classes error variable that was storing ec.error(); and corrected in my main class method errorMsg of ErrorCheck.java as following:

String finalSubject = error()+subject;
        StringWriter sw = new StringWriter();  
                PrintWriter pw = new PrintWriter(sw);  
                    e.printStackTrace(pw);

Now its working fine
