I've been testing James' database repository code, and it seems to me that excalibur's datasource is non-blocking (or something strange). If too many threads try to get a connection at once, I get the following stack trace:
java.lang.InstantiationException: Ran out of resources to instantiate at org.apache.avalon.excalibur.pool.HardResourceLimitingPool.newPoolable(HardRe sourceLimitingPool.java:98) at org.apache.avalon.excalibur.datasource.JdbcConnectionPool.newPoolable(JdbcCo nnectionPool.java:52) at org.apache.avalon.excalibur.pool.AbstractPool.internalGrow(AbstractPool.java :113) at org.apache.avalon.excalibur.pool.DefaultPool.get(DefaultPool.java:125) at org.apache.avalon.excalibur.datasource.JdbcConnectionPool.get(JdbcConnection Pool.java:76) at org.apache.avalon.excalibur.datasource.JdbcDataSource.getConnection(JdbcData Source.java:181) at org.apache.james.mailrepository.JDBCMailRepository.getConnection(JDBCMailRep ository.java:576) Any ideas? Ideally if I ask for a connection and I'm at the max number of connections, it waits and tries again rather than throwing this exception. I see it's using HardResourceLimitingPool, and so maybe SoftResourceLimitingPool should be used instead? Just not sure why hard was picked and/or the theory behind this connection pooling.
