I am writing tests which run OkHttp/Retrofit requests against a MockWebServer. Among other things I'm testing timeouts. Here I noticed, that some of my timeout tests do not produce the same kind of exception all the time:
While the exception thrown is always a SocketTimeoutException, the exception message differs between two possibilities. Sometimes I get
"timeout", sometimes
"Read timed out".
There seems to be no clear pattern (it's the very same test which sometimes produces one or the other of these exception messages).
I assume that different constellations/causes lead to the differing messages... Can somebody explain to me the difference between these two cases?
Here are the corresponding stack traces:

In case jOOQ can't connect to a database, executing SQL against it will result in a DataAccessException.
Is there a way to get the url of the database/connection against which the query was attempted, just from this error?
Edit, adding more context:
We have a simple connection pooling implementation using a HashMap and its computeIfAbsent().
If DSL.using(url) does not throw an Exception, we consider the connection established and keep the resulting DSLContext as value in said map (url is key).
Assume there are multiple connections in the pool.
We have an ExecuteListener attached to the DSLContext and in it, we catch DataAccessExceptions. When caught, we validate the connection with: executeContext.dsl().diagnosticsConnection().isValid(1).
If the connection became invalid, we would like to flag it as such but the only way to find out which one it is, is to loop over the connection pool map because executeContext.dsl().parsingConnection().getMetaData().getURL() is no longer an option.
Here's an example stack trace. It's different for each of the DB engines we connect to but always wrapped in org.jooq.exception.DataAccessException.

Thanks for your help, I found the bug. FYI see https://github.com/neo4j/neo4j/pull/8778 for fix.
Thanks to this question I know that I need to specify errorHandler(noErrorHandler()) in a sub-route in order for exceptions to be propagated to the parent route in Camel. However I would like to handle some exceptions in the sub-route but propagate the rest to the parent.
For example:
from("direct:top")
.onException(Exception.class)
.log("Top-level: ${exception}")
.continued(true)
.end()
.to("mock:start")
.to("direct:sub1")
.to("direct:sub2")
.end();
from("direct:sub1")
.errorHandler(noErrorHandler())
.to("mock:sub1")
.throwException(new IllegalArgumentException("test"));
from("direct:sub2")
.onException(IllegalArgumentException.class)
.log("Sub2: ${exception}")
.continued(true)
.end()
// but I want all other exceptions to be propagated to the top handler
.to("mock:sub2")
.throwException(new IllegalArgumentException("test"))
.throwException(new NullPointerException("test"));
sub1 works as expected, but I'd like sub2 to locally handle and log the IllegalArgumentException and allow the NullPointerException to bubble up to the parent. However, my log output looks like this:
10:35:28.048 [main] INFO route1 - Top-level: java.lang.IllegalArgumentException: test
10:35:28.049 [main] INFO route3 - Sub2: java.lang.IllegalArgumentException: test
10:35:28.056 [main] ERROR DefaultErrorHandler - Failed delivery for (MessageId: xxxx on ExchangeId: xxx). Exhausted after delivery attempt: 1 caught: java.lang.NullPointerException: test
If I add errorHandler(noErrorHandler()) to sub2 the IllegalArgumentException is propagated to the parent (which I don't want) and the NullPointerException isn't logged at all. Is there any way to achieve my desired behaviour?
When you throw an exception the exception is cought and route ends immediately, so the second exception can't be thrown. If you want to throw the second exception only if the first one occurs you should throw it from onException block (before .end)
I have been running a simple Junit testclass with a single test method.
I am stuck with the below error.
The stackTrace is as follows

I did not have to add any jar files to the CLASSPATH though. I solved it by adding the following system property:
-Dorg.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.SLF4JLogFactory
is this mandatory in running the webservices through JUNit?
I have an application which throws "Exception of type 'System.OutOfMemoryException'". Which reduces the performance of the server,the CPU usage was around 95%.
I dont know the reason why this problem is occuring ....
can any one pls tell wats the reason for the error and how can i sort it out????
This is my stack trace:
