FileCleaningTrackerTestCase hangs
---------------------------------
Key: IO-161
URL: https://issues.apache.org/jira/browse/IO-161
Project: Commons IO
Issue Type: Bug
Components: Utilities
Affects Versions: 1.4
Environment: Linux sliver.usr.dsi.unimi.it 2.6.22.14-72.fc6 #1 SMP Wed
Nov 21 15:12:59 EST 2007 i686 i686 i386 GNU/Linux
java version "1.5.0_10"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03)
Java HotSpot(TM) Client VM (build 1.5.0_10-b03, mixed mode, sharing)
Reporter: Sebastiano Vigna
The following code in FileCleaningTrackerTestCase never exits, hanging the
whole compilation/testing process:
private void waitUntilTrackCount() {
while (theInstance.getTrackCount() != 0) {
int total = 0;
while (theInstance.getTrackCount() != 0) {
byte[] b = new byte[1024 * 1024];
b[0] = (byte) System.currentTimeMillis();
total = total + b[0];
System.gc();
}
}
}
It is clear that in theory this code might loop forever, as the allocation of
the byte arrays might never unleash a garbage collection complete enough to
deallocate all marker objects, so to bring the track count to zero. Believe me,
it's not only theory :).
