------------------------------------
Summary: EXSLT function Date:Date throws IndexOutOfBounds
Exception on empty input
Key: XALANJ-2584
URL: https://issues.apache.org/jira/browse/XALANJ-2584
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in
Xalan projects. Anybody can view the issue.)
Components: Xalan
Affects Versions: 2.7.2
Reporter: Philip Miess
Assignee: Steven J. Hathaway
Priority: Minor
When running the following XSL file Xalan-J throws
bq. java.lang.StringIndexOutOfBoundsException: String index out of range: 0 -
String index out of range: 0
As long as the root node does not have an attribute named "anAttribute".
Expected output is an single root node
[ExsltDatetime.html|https://xalan.apache.org/xalan-j/apidocs/org/apache/xalan/lib/ExsltDatetime.html#date(java.lang.String)]
indicates that it should produce an empty string instead of throwing
bq. If the argument is not in either of these formats, date:date returns an
empty string ('')
Saxon produces the expected output.
If the null check where moved to the start of the date function it world work
as specified.
