Kathey Marsden closed DERBY-4252.
---------------------------------
Resolution: Cannot Reproduce
I am not able to reproduce this on trunk with the latest IBM JVM.
> intermittent corruption./java.io.EOFException in RandomAccessFile.readInt()
> on boot after compress with background checkpoint

> Key: DERBY-4252
> URL: https://issues.apache.org/jira/browse/DERBY-4252
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.6.1.0
> Environment: Windows XP dualcore.
> java version "1.6.0"
> Java(TM) SE Runtime Environment (build pwi3260sr4-20090219_01(SR4))
> IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 Windows XP x86-32
> jvmwi3260-20090215_29883 (JIT enabled, AOT enabled)
> J9VM - 20090215_029883_lHdSMr
> JIT - r9_20090213_2028
> GC - 20090213_AA)
> JCL - 20090218_01
> Also tried with the latest development SR5 version and it reproduces.

> The attached reproduction reproBackgroundCheckpoint.zip occasionally results
> in an EOF exception on boot with IBM 1.6 (about 1 out of 200 runs) even
> after the fix for DERBY-4239. The program inserts into /deletes some data
> from a table and runs compress, and as a daemon thread that loops
> checkpoints. I have not seen it with the Sun JVM.
> Before the fix for DERBY-4239, this issue was much more frequent. Sometimes
> you would get the DERBY-4239 trace and sometimes this one. After the fix,
> this issue remains. Mike thought it looked like a different bug and asked
> that we file a separate issue.
