Re: [lang] StrSubstitutor - a dollar sign before a variable
Gotcha! Now I can understand the escape character means: Ignore the
following variable reference.
Thank you so much for the explanation with a good solution.

To explain a little more, consider what happens to $${amount} when
you're using StrSubstitutor's default escape character. StrSubstitutor sees
that you've got a variable reference (${amount}), and that you've got the
escape character ($) before it, so it replaces $${amount} with
${amount}.
Now consider what happens to $${amount} when you've set StrSubstitutor's
escape character to something other than the default. StrSubstitutor sees
the variable reference (${amount}), notes that the character ($) before
the variable reference is _not_ the user-defined escape character, and so
replaces ${amount} with the appropriate value form the map.

From the javadoc: If
[dbcp] Abandon Connection - not Logging in standalone
Hello, I noticed that with Oracle drivers you cannot kill a busy connection by closing it (since close(), _getPC(), isOpen() and stmt.close() all will synchronize on the (busy) physical connection. I noticed this in a custom persistence layer, so I thought to check out if DBCP handles this situation. I have a test program here: https://gist.github.com/ecki/345ee08ac97820972fe7 First of all it does not log DBCP messages. I am not sure what is needed to get it going. As you can see in the output the deliberate debug() message is printed so the general LogFactory should be set up. When I run the program with acfg.setRemoveAbandonedTimeout(12) it suceeds, since the c3 is only idle for 10s. When I run it with (4) it will (so it seems) close the connection and I get a exception on next use. However I dont see a log message about the abandoned connection and the usage tracking. Ideas? A second thing, from the abandoned tracker I had the impression the usage is counted at the begin of exec. So if a execution takes 20s as in my case, it should be considered abandoned. But it seems not to be the case. Is it recognizing it is busy when the exec does not return? If this is the case, is there also a way to kill/destroy connections beeing used too long?

From the javadoc: If this character ['$'] is placed before a variable

To achieve your desired effect, I think you either have to put the dollar

Re: [lang] StrSubstitutor - a dollar sign before a variable
The escape character just tells StrSubstitutor Ignore the following
variable reference. When you change the default escape character, you
don't need to use it get a dollar sign before a variable reference in your
interpolated string. Try the following:
@Test
public void testReplaceEscapingDollarSign() {
values.put(amount, 20.00);
final StrSubstitutor sub = new StrSubstitutor(values);
sub.setEscapeChar('');
String replaceTemplate = The ${animal} jumps over the ${target}.;
String expectedResult = The ${animal} jumps over the lazy dog.;
String replacedResult = sub.replace(replaceTemplate);
assertEquals(expectedResult, replacedResult);
replaceTemplate = The ${animal} paid $${amount} to jump over

expectedResult = The quick brown fox paid $20.00 to jump over
