> The problem occurs when we have a security manager enabled with restrictions.
> After writing a request to
> [LdapNetworkConnection|https://github.com/apache/directory-ldap-api/blob/52129503d7f2247bad4a5f73b234023b8158ff07/ldap/client/api/src/main/java/org/apache/directory/ldap/client/api/LdapNetworkConnection.java#L4934],
> we wait for the completion of the request. For every
> {code:java}writeFuture.awaitUninterruptibly{code} it checks for deadlock
> [DefaultIoFuture|https://mina.apache.org/mina-project/apidocs/src-html/org/apache/mina/core/future/DefaultIoFuture.html]#checkDeadLock()
> which is code that requires security permissions and throws following
> exception:
> {code:java}java.security.AccessControlException: access denied
> ("java.lang.RuntimePermission" "accessClassInPackage.sun.reflect"){code}
> A proposed solution would be to ignore Java security manager exception (SME)
> similar to Class not found exception(CNFE). For CNFE, we ignore the exception
> and continue as we are just testing for deadlocks.
> {code:java}
> for (StackTraceElement s : stackTrace) {
> try {
> Class<?> cls =
> DefaultIoFuture.class.getClassLoader().loadClass(s.getClassName());
>
> if (IoProcessor.class.isAssignableFrom(cls)) {
> throw new IllegalStateException("DEAD LOCK: " +
> IoFuture.class.getSimpleName()
> + ".await() was invoked from an I/O processor
> thread. " + "Please use "
> + IoFutureListener.class.getSimpleName()
> + " or configure a proper thread model
> alternatively.");
> }
> } catch (ClassNotFoundException cnfe) {
> // Ignore
