I am getting the below stack trace of the error I am getting.

I am using hibernate-core-3.6.0-Final jar in my code. When I searched in internet, it is suggested to modify the piece of code as below:

    if ( String.class.isInstance( value ) ) {
             final String str = (String) value;
            return Character.valueOf( str.charAt(0) );
          }

should be replaced with

    if ( String.class.isInstance( value ) ) {
             final String str = (String) value;
             if ( str.length() == 0 ) {
                return null;
             }
             return Character.valueOf( str.charAt(0) );
          }

.

I tried to do so. But unable to do it. So Shall I downgrade to hibernate-core-3.5.6-Final jar to avoid the said exception ?. Will it cause any issue ?.

  • Current hibernet version is :`'5.4.24.Final'`, instead of down-grading try upgrading the library. https://mvnrepository.com/artifact/org.hibernate/hibernate-core – MD Ruhul Amin Nov 19 '20 at 14:01
  • my project will not support latest version of jar. Or else can you please advice me to avoid the error ? – Chandruma Sampath Nov 19 '20 at 14:03
