Sergii Angelov created POOL-290:
-----------------------------------
Summary: TestSoftRefOutOfMemory goes into infinite loop
Key: POOL-290
URL: https://issues.apache.org/jira/browse/POOL-290
Project: Commons Pool
Issue Type: Bug
Reporter: Sergii Angelov
When running TestSoftOutOfMemory tests, application goes into infinite loop in
case if OutOfMemoryError happens. It happens for each function that tests
OutOfMemory case.
For example in this code
{code}
while (pool.getNumIdle() > 0) {
try {
long freeMemory = runtime.freeMemory();
if (freeMemory > Integer.MAX_VALUE) {
freeMemory = Integer.MAX_VALUE;
}
garbage.add(new byte[Math.min(1024 * 1024, (int)freeMemory/2)]);
} catch (OutOfMemoryError oome) {
System.gc();
}
System.gc();
}
{code}
Correct me if I'm wrong, but wouldn't it be more efficient to destroy pool
immediatelly if error happens and wait till we free that piece of memory (for
example wait till free memory increased by the size of current pool).
