------------------------------------
Jochen, here is the result of java compilation. Only two exception table to
handle exceptions:
{code}
TRYCATCHBLOCK L0 L1 L2 null
TRYCATCHBLOCK L0 L3 L4 java/lang/Exception
{code}
{code}
// Java code
public static void main(String[] args) {
try {
try {
System.out.println("try!!!");
} finally {
System.out.println(99 / 0);
}
} catch (Exception e) {
System.out.println("catch!!!");
}
}

> Exception in "finally" not caught by outer "try"
> ------------------------------------------------
>
> Key: GROOVY-8085
> URL: https://issues.apache.org/jira/browse/GROOVY-8085
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.8
> Environment: linux
> Reporter: Craig Silverstein
>
> I would expect the following code to print `caughtt`:
> ```
> groovy -e 'try { try { true; } finally { 1 / 0 } } catch (e) { println
> "caughtt" }'
> ```
> But instead, it prints:
> ```
> Caught: java.lang.ArithmeticException: Division by zero
> java.lang.ArithmeticException: Division by zero
> at script_from_command_line.run(script_from_command_line:1)
> ```
> Why is the exception, thrown by the `finally`, not being caught by the outer
> try/catch?
