Bug ID: 62287
Summary: ValueExpressionImpl#equals is wrong
Product: Tomcat 9
Version: 9.0.6
Hardware: PC
OS: Mac OS X 10.1
Status: NEW
Severity: normal
Priority: P2
Component: EL
Assignee: dev@tomcat.apache.org
Reporter: strub...@apache.org

patch for ValueExpressionImpl
ValueExpressionImpl#equals is likely not enough.
The current code just compares the hashCode():
>return (obj instanceof ValueExpressionImpl && obj.hashCode() ==
>this.hashCode());
It's possible that there is the same hashCode for different objects. For some
Java Classes we alwasy get 0 even.
For better tracking: this came up during a bug report against Apache
OpenWebBeans as reported by Holger Sunke.
