The Bug is still open, maybe someone could look to the patch applied.

It works now for serveral month very good for me.

Is it possible to undefine Operations.

try{
 feature = TypeUtil.defineOperation(	
contextEnv.getContextClassifier(),				
unquote(operCS.getSimpleNameCS().getValue()),
params, type);
expression = oclExpressionCS(defExpr.getExpressionCS(), contextEnv);	
}catch (SemanticException e) {	
//undefine the operation
throw e;
}


Here the actual patch:
