Niklas Matthies created NETBEANS-34:
---------------------------------------
Summary: "Too broad 'catch' clause" hint doesn't properly support
generic 'throws' declarations
Key: NETBEANS-34
URL: https://issues.apache.org/jira/browse/NETBEANS-34
Project: NetBeans
Issue Type: Bug
Components: java - Hints
Affects Versions: 8.2
Reporter: Niklas Matthies
Example:
{code:java}
class Example
{
<T extends Throwable> void foo() throws T { }
void bar() throws CertificateException { }
void example()
{
try {
this.<GeneralSecurityException> foo();
bar();
}
catch (GeneralSecurityException ex) {
// ignore
}
}
}
{code}
NetBeans shows the following hint: "The
catch(java.security.GeneralSecurityException) is too broad, the actually caught
exception is java.security.cert.CertificateException". Which is incorrect,
because the call to foo() throws a GeneralSecurityException.
Furthermore, when adding a second catch clause specifically for
CertificateException (before the existing catch clause), the hint on the
existing catch clause becomes: "The
catch(java.security.GeneralSecurityException) is too broad, it catches the
following exception types: null".
