Subject: [Hsqldb-developers] Access
violation in VM with HSQLDB 1.7.2 RC 6b
I'm running the test again, but the following code crashed
with a VM EXCEPTION_ACCESS_VIOLATION:
ResultSet r = statement.executeQuery("Select * from ARP order
by IFPHYSADDRESS");
boolean bContinue =
r.next();
while (bContinue) {
String currentMac = r.getString(4);
pw.println("Mac Address " + currentMac + " belongs to " +
r.getString(5));
do {
pw.println("Seen By: +
r.getString(2) + " on Interface " + r.getInt(3));
//
^ This field gets printed to the log file, but the rest of the line is
incomplete.
bContinue = r.next();
}
while (bContinue &&
currentMac.equalsIgnoreCase(r.getString(4)));
}
r.close();
The code runs with a large data file (1.5GB), and I get about
8MB of output from the printlns until the crash.
From
the source, I don't see anything that would cause this, but perhaps someone
else has a better understanding of the code.
Thank you for your time.
