- 

caused by: com.some.packge.mycustomexception: blah, blah, blah

how can sub-string of above string in such way blah blah part. tried below mycustomexception in substring.

mainstring.substring(mainstring.indexof("mycustomexception"));

you can this: 

mainstring = mainstring.substring(mainstring.indexof("mycustomexception:") + "mycustomexception:".length());

you should check if string contains mycustomexception: before that.
