[Condor-users] Is this a bug of classad java library?

["yaoheng zhang" <yaoheng.zhang@xxxxxxxxxxxx>]

Hi all,

 

I am doing my application with ClassAd java library from http://www.cs.wisc.edu/condor/classad/.

 

The ClassAdParser.parse() throws IllegalArgumentException when parsing the result of condor_q –xml:

 

java.lang.IllegalArgumentException: null value for attribute Iwd

            at condor.classad.RecordExpr.insertAttribute(RecordExpr.java:130)

            at condor.classad.ClassAdSAXHandler.addElement(ClassAdSAXHandler.java:264)

            at condor.classad.ClassAdSAXHandler.endElement(ClassAdSAXHandler.java:203)

            at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(AbstractSAXParser.java:633)

            at condor.classad.ClassAdParser.parse(ClassAdParser.java:272)

            at condor.classad.ClassAdParser.parse(ClassAdParser.java:297)

 

The code works well in Linux but always throws this exception in my windows xp. I noticed the parser only cannot deal with the “Iwd” and “Userlog” maybe because the values are windows path.

 

At condor.classad.ClassAdSAXHandler.endElement(ClassAdSAXHandler.java:203), Constant.unquoteString(String) method returns null when the parameter is the path string like “E:\\condor\\my”.  The cause is in the method Constant.unquoteString(char[], int, int), where the “\\c” is illegal.  I think the string is good enough and doesn’t need to be unquoted….not sure….

 

Anyone can help?
