I have a suggestion. I used the same approach in the expressions module to
patch the stack trace and rethrowing exceptions (to include the source code of
the exception into the stack trace). So basically at moment you always use code
like this:
```java
} catch (Throwable t) {
IOUtils.closeWhileSuppressingExceptions(t, docIn, posIn, payIn);
throw t;
}
```
It would be much nicer like this:
```java
} catch (Throwable t) {
throw IOUtils.closeWhileSuppressingExceptions(t, docIn, posIn, payIn);
}
```
This can be done by using generics on the method:
```java
public static <T extends Throwable> T closeWhileSuppressingExceptions(T
ex, Iterable<? extends Closeable> objects) {
for (Closeable object : objects) {
try {
if (object != null) {
object.close();
}
} catch (Throwable e) {
ex.addSuppressed(e);
}
}
return ex;
}
```
This allows the compiler to still take record of the exceptions and the code
looks much better because you actually see that the method modifies the
exception.
If you don't want to use the return type, you can still rethrow the
conventional way.
