Debug level Hibernate log excerpt:

Problem is that PrimitiveType breaks when attempting to log the RuntimeException.

From NullableType.java, line 87 ;-

catch ( RuntimeException re ) {
log().info( "could not bind value '" + toString( value ) + "' to parameter: " + index + "; " + re.getMessage() );
throw re;
}

The PrimitiveType.toString method is ;-

public String toString(Object value) {
return value.toString();
}

and will not break if amended to ;-

public String toString(Object value) {
return String.valueOf(value);
}

I have searched JIRA etc. and the closest that I could find was HHH-1366
(I am a Hibernate newbie ).

TIA

Fixing the toString() methods in package org.hibernate.type produced the following trace ;-

Exception in thread "main"

Edit org.hibernate.auction.Main in folder eg ;-

User bidder2 = new User();
bidder2.setUserName("steve");
bidder2.setName( new Name("Steve", null, "Ebersole") );
bidder2.setEmail("steve@hibernate.org");
bidder2.setPassword("******");

Fix the problem by changing bidder2.setName to ;-

bidder2.setName( new Name("Steve", new Character(' '), "Ebersole") );
