Many of the largest customers out there prefer a completely stable environment, so bumping the minimum Java version can’t be done yet.
But yet again no one is blocked. It’s a different package name and you can control which one you use.
However if there is even one of other person being affected by this obscure eviction run issue, we would like to hear about that (just post here).

Hi Isomorphic,
I had a look at the lib folder of 13.0d and saw that you bumped a few libs and also removed some and added others.
Unfortunately this one is not one of the changed ones. As I pointed out in #4, there won't be a new version of Apache Commons DBCP 1.4.
I saw you current readme.html, which still speaks of a minimum requirement of Java 1.5 - I think here it should be safe to say that new development should be using at least Java 8 (or even 11?), which would allow you to use current DBCP 2.7.0. You say similar things to your users and it's completely reasonable in both cases IMHO.
While we are no longer affected by the issue, as we use JNDI now with a more current version of DBCP (via tomcat-dbcp), that is automatically bumped with Tomcat versions (search for "dbcp" here), it would be nice for all other users, that use your default configuration, to be not affected by the issue.
Also - and possibly more important - it looks very bad when evaluating frameworks when the dependencies are very EOL.
Best regards

Just a FYI for everyone hitting this thread via search. We are now using JNDI and with this Tomcat's current built-in DBCP (see a few times here when you search for "commons"). This is working and also saving a connection needed otherwise for login.
Nevertheless I do think that it is a good idea to have current versions of the dependencies, that are not EOL, see #6.

You aren’t blocked, it’s a different package name.
So it looks like the only problem continues to be the obscure bug involving eviction runs which they appear to have fixed (but not yet released) in 1.x. Let us know if we’ve missed something.

Hi
We too would like to upgrade our DBCP dependency but we're blocked by the fact that SmartGWT depends on it.
Possibly we can run both versions in parallel, we haven't tried that path yet (but I don't think it's ideal either).
DBCP 1.4 is really old and there is no support on it anymore. JIRA tickets are referred to newer versions.
So +1 for a dbcp upgrade.
Thanks

Hi Isomorphic,
I understand that it is not possible to do such a change in a 12.0p nightly. With nearly-out releases I assume you refer to 12.1d/p, which is of course bad from my point of view. So you are saying you plan a change for next next major release?
IF the minIdle: 0 change fixes it for me, I'm happy with 1.4 as well. IF our planned switch Oracle->Postgres does invalidate the necessity of timeBetweenEvictionRunsMillis at all, I'm also happy with 1.4. So let's hope that this is the case. If not, building from source, which I already considered, might be a last resort.
And while I'm a big fan of keeping proven solutions, I also think that it is a good idea if you updated all your used libraries at least to the state where you use a version that is in active development, so that jar-file.version bumping becomes possible if ever necessary.
I did not check all Apache commons and other used libraries, but for some there are already versions with namespace changes out, so if there appears a bug in such an unmaintained version, there will be a problem like now.
Best regards

Actually they seem to indicate the bug has been fixed, but not released, so perhaps there's hope. There's always the (painful) path of building it yourself from source.
There's a not a lot we can do for you here in the immediate term, as DBCP2 is not just a minor version bump but a replacement library with major internal differences. We will of course switch over sometime soon, but we can't switch existing or nearly-out releases to the new library, not when the only problem with the existing library is a feature that, so far, not even one other user seems to need. Sorry that this is a problem for you.

Hi Isomorphic,
chances for a 1.4.1 are bad, see here, where they are suggesting to switch to 2.6.0.
1.4 is more than 9 years old now and commons.dbcp2 is in active development since 2014 with ~2 releases a year.
For now, I tried setting sql.pool.minIdle: 0 as they claim that positive minIdle and timeBetweenEvictionRunsMillis together will trigger the issue. I'll watch if this mitigates the problem successfully.
Best regards

DataSourceManager.get() does involve a DBCP pool. So it looks like you will need to turn off eviction runs until 1.4.1 comes out.

Problem with Apache DBCP and maxed out pool
Hi Isomorphic,
it seems we do have a problem with current 12.0p (v12.0p_2019-03-23) and the shipped commons-dbcp-1.4.jar.
It is likely that this is related to this thread and the DBCP issue you mention in #6 there.
Release notes for unreleased Apache Commons DBCP 1.4.1 mention the bug that 1.2.2 claims to have fixed. It contains this fix which claims that the fix in 1.2.2 is incomplete. Now 1.4.1 is unreleased, so there is not much you can do here. I did ask for a release date, though. But I do assume that DBCP 2 (new namespace) fixes it as well, as this is in active development (3 releases in 2018, 1 in 2019).
We do have the configuration in place that is said to cause the issue (positive minIdle and timeBetweenEvictionRunsMillis):
Code:sql.defaultDatabase: Oracle sql.useAnsiJoins: true # Apache Commons DBCP Database connection pooling sql.pool.enabled: true [B]sql.pool.minIdle: 1[/B] sql.pool.maxActive: 10 sql.pool.whenExhaustedAction: block sql.pool.testWhileIdle: true [B]sql.pool.timeBetweenEvictionRunsMillis: 15000[/B] sql.pool.minEvictableIdleTimeMillis: 29000 sql.Oracle.database.type: oracle sql.Oracle.autoJoinTransactions: true sql.Oracle.database.supportsSQLLimit: false sql.Oracle.interface.credentialsInURL: true sql.Oracle.interface.type: dataSource sql.Oracle.pingTest: select 1 from dual sql.Oracle.driver: oracle.jdbc.pool.OracleDataSource sql.Oracle.driver.url: jdbc:oracle:thin:@xxxxxx:1521/DB11GXDB.localdomain sql.Oracle.driver.user: xxx sql.Oracle.driver.password: xxx sql.Oracle.driver.driverType: thin sql.Oracle.driver.networkProtocol: tcp sql.Oracle.driver.context:
We run many instances of our application as own WAR files. These application run on the same Tomcat (9.0.17). Now if the issue happens, one application (server.xml <Host> entry) maxes out it connections. New requests will hang (stack trace follows). This in turn maxes out our Tomcat threads (maxThreads here) eventually, bringing all instances effectively down, as no more threads can be created.
We restarted our application to prevent the "whole Tomcat down" issue from happening.
At that time, we had many (~50) BLOCKED threads, most of them with a stack trace where the top line is like this (there are of course many different codepaths that use DB connections in the end, so the whole stack is always a bit different:
