TomEE DataSource configuration does not honour actual configuration



    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 1.5.1
    • Fix Version/s: 1.6.0
    • Component/s: None


      The Tomcat "StatementCache" jdbc interceptor is always added, no matter what the actual configuration is. Following the TomEE documentation, the following default DataSource property values are added to each created DataSource :
      PoolPreparedStatements=false, MaxOpenPreparedStatements=0

      The method TomEEDataSourceCreator.updateProperties(SuperProperties, Properties, String) at line 138 checks for the presence of the "MaxOpenPreparedStatements" or "PoolPreparedStatements" properties. If they are present, the StatementCache "jdbcInterceptors" property is added to the properties passed on to Tomcat. The test to add the StatementCache is wrong: StatementCache should be added only if PoolPreparedStatements == true and NOT if the "PoolPreparedStatements" property is merely present since it's always the case.

      Also, in the same method between lines 101 and 112, there is unreachable code. Here is the code:
      final String maxWait = toMillis((String) properties.remove("maxWaitTime"));
      if (properties.containsKey("maxWaitTime") && !properties.containsKey("maxWait")) {
      converted.setProperty("maxWait", maxWait);
      final String tb = toMillis((String) properties.remove("timeBetweenEvictionRuns"));
      if (properties.containsKey("timeBetweenEvictionRuns") && !properties.containsKey("timeBetweenEvictionRunsMillis")) {
      converted.setProperty("timeBetweenEvictionRunsMillis", tb);
      final String minEvict = toMillis((String) properties.remove("minEvictableIdleTime"));
      if (properties.containsKey("minEvictableIdleTime") && !properties.containsKey("minEvictableIdleTimeMillis")) {
      converted.setProperty("minEvictableIdleTimeMillis", minEvict);

      In each case, the property is removed and then we check if it's there. This test cannot pass. The first condition of each "if" statement should be of the following form, taken a few lines above in the same file:
      final String user = (String) properties.remove("user");
      if (user != null && !properties.containsKey("username")) {
      converted.setProperty("username", user);
