core: Consolidate duplicate exception handling
This patch removes duplicate blocks of exception handling.
The pattern this patch addresses is the following:
try {
someFunction();
} catch (SomeException e) {
handleException(e);
} catch (SomeBaseException e) {
handleException(e);
}
If SomeException inherits from SomeBaseException, this construct is
completely redundant (regardless of Java version), and should be
simplified to just handle SomeBaseException:
try {
someFunction();
} catch (SomeBaseException e) {
handleException(e);
}
If SomeException does not inherit from SomeBaseException, this
construct is still difficult to read, and could be simplified using
Java 7 syntax:
try {
someFunction();
} catch (SomeBaseException | SomeException e) {
handleException(e);
}
