PM10208: CLASSCASTEXCEPTION THROWN FOR VALIDATE IN VARIABLE DECLARATION

APAR status

• Closed as program error.

Error description

• A ClassCastException is thrown if a validate expression that
  specifies one of the optional 'lax' or 'strict' keywords
  appears in  initialization expression for a variable
  declaration.  Given any input, the following  query yields the
  error "com.ibm.xtq.ast.parsers.xpath.
  tempconstructors.ISimpleNodeWithValue
  incompatible with com.ibm.xtq.ast.nodes.Expr"
  
  
  declare variable $x := validate lax { <a/> };
  
  $x

  * PROBLEM DESCRIPTION: ClassCastException for XQuery           *
  *                      validate expression                     *

  ****************************************************************
  A ClassCastException occurs if a validate expression that
  specifies one of the optional 'lax' or 'strict' keywords
  appears in initialization expression for a variable
  declaration in XQuery.  For example, given any input, the
  following query will cause a ClassCastException with the
  message
  "com.ibm.xtq.ast.parsers.xpath.tempconstructors.ISimpleNodeWithV
  alue
  incompatible with com.ibm.xtq.ast.nodes.Expr"
  
  declare variable $x := validate lax { <a/> };
  
  $x
  

Problem conclusion

• The processor now correctly processes such variable
  initialization expressions without raising an exception and
  produces the correct result.
  
  This APAR is currently targeted for inclusion in the Feature
  Pack for XML 1.0.0.5.  Please refer to the Recommended Updates
