We found a minor bug in java.io.File when we tried to run Volano benchmark on ORP
with Classpath.
Here's the senario:
File file = new File(System.getProperty(propname), filename);
While System.getProperty(propname) return null, then the constructor:
File(String dirname, String name){
this(dirname + separator + name);
}
assumes that a file with filename must exist under the directory named
"null".
An approperiate modification is to add a check like this:
this(dirname == null?name:dirname + separator + name);
The context compare result below is based on gnu classpath cvs snapshot of June
22.Note that revision number is different from public CVS.
