Hi,
I have a wierd situation.
The method is syncronized and the List is also Syncronized, but I get a
ConcurrentModificationException exception.
Appreciate your help.
Thanks & regards,
Ebe
Camel Route:
from("file:/vzwhome/c0sineb/work_dir/camel_proj/data/input?delete=true")
//from("file:C:\\camelProject\\data\\inbox?delete=true")
.log("Starting to process big file: ${header.CamelFileName}")
.split(body().tokenize("\n")).streaming()
.aggregate(header("CamelFileName"), new
MyListAggregation()).completionSize(2000)
.parallelProcessing()
.executorService(threadPool)
.bean(ListParser.class,"parseList")
ListParser class:
The line 16 in the below error log is in *Bold*
public synchronized StringBuilder parseList(List<String> myList) {
List<String> syncList = Collections.synchronizedList(myList);
logger.info("Size of MyList : "+syncList.size());
StringBuilder result = new StringBuilder();
try{
*for(String in_str: syncList){*
result.append("&").append(parseString(in_str));
}
}catch(Exception ex){
logger.error("Error parsing List",ex);
}
return result;
}
For some reason I get the below error
