There was a case where if the transaction timed out and
rolls back before the application returned from an ejb which
suspended the transaction, then the application tried to
use the connection, they would get a cm exception:
TransactionAbortedException, but the connection would be
leaked.
use the connection, they would get a cm exception:TransactionAbortedException, but the connection would beleaked.
Problem conclusion
Corrected the code so that in the case where the transaction
timed out, the connection is freed and returned to the pool
correctly.
Temporary fix
