Myrna van Lunteren commented on DERBY-6248:
-------------------------------------------
To give an update on some further experiments/debugging:
- this problem did not surface in 50 runs with either Oracle's jdk 1.8 nor jdk
1.6.
- with both of those, an additional SQLCARD (from DRDAConnThread.writeSQLCARDs)
is written on the server over what happens with ibm 1.6 (or 1.7) jvms (fail or
passing run)
- with ibm 1.6, when the failure occurs, EmbedPreparedStatement.finalize()
doesn't get called until right before the error happens. (and
EmbedStatement.finalize() just after). In passing runs, these methods get
called sooner. With jdk 1.8, these methods apparently do not get called at
all... (Of course, the calling of these finalize methods are as likely a
symptom as the cause of the problem).
