---------------------------------
Summary: Add infomation about exceptions thrown inside empty
function
Key: JEXL-459
URL: https://issues.apache.org/jira/browse/JEXL-459
Project: Commons JEXL
Issue Type: Wish
Affects Versions: 3.6.2
Reporter: Mirek Hankus
Currently empty function swallows all exceptions
{code:java}
@Override
protected Object visit(final ASTEmptyFunction node, final Object data) {
try {
final Object value = node.jjtGetChild(0).jjtAccept(this, data);
return operators.empty(node, value);
} catch (final JexlException xany) {
return true;
}
} {code}
I'd like to have ability to log information about such exceptions. For example
expression
{code:java}
empty('aaa'.substring(400,500)) {code}
returns true, but it is very costly operation.
Please add something like
{code:java}
if (isSilent() && logger.isWarnEnabled()) {
logger.warn(xany.getMessage(), xany.getCause());
} {code}
or any other way of logging problems in expressions.
similar problem is with size - which also ignores all exceptions
{code:java}
@Override
protected Object visit(final ASTSizeFunction node, final Object data) {
try {
final Object val = node.jjtGetChild(0).jjtAccept(this, data);
return operators.size(node, val);
} catch (final JexlException xany) {
return 0;
}
} {code}
