[jira] Created: (HARMONY-2502) [DRLVM] Runtime exception in fast
path helpers crashes DRLVM.
[DRLVM] Runtime exception in fast path helpers crashes DRLVM.
-------------------------------------------------------------
Key: HARMONY-2502
URL: http://issues.apache.org/jira/browse/HARMONY-2502
Project: Harmony
Issue Type: Bug
Components: DRLVM
Reporter: Pavel Afremov
The following simple test can crash DRLVM (VM crashes without any message) :
class ConstructorStackTest {
private static final int MAX_DEPTH = 1000000;
ConstructorStackTest(int c) {
if (c > 0) {
new ConstructorStackTest(c - 1);
}
}
public static void main(String[] args) {
try {
new ConstructorStackTest(MAX_DEPTH);
System.out.println("PASS");
} catch (StackOverflowError soe) {
System.out.println("PASS : " + soe);
} catch (Throwable th) {
System.out.println("FAIL");
}
}
}
The source of the crash is in throwing StackOverflowError in fast path GC helper, where M2n frame is not created. To fix this bug required implement support of runtime exceptions in runtime helper or rewrite this helpers on "magic".

[jira] Commented: (HARMONY-2502) [drlvm] Runtime exception in fast

-------------------------------------------
Tue May 22 17:21:20 RDT 2007
The issue is still reproducible on Windows/x86.
It does not crash anymore (still it prints neither "PASSED" not "FAILED") and exit code is 128.
Thanks
