Description

try simple malformed filter like 'blah' and see what happends:

line 1:1: expecting LPAREN, found 'blah'

This is printed out to system.err and no exception results. This is not good because it can hang indefinately.

Is it possible to get more info on this?

Within my test cases, I have some search operations here:
https://svn.apache.org/repos/asf/directory/trunks/testsuites/src/main/java/org/apache/ldap/testsuite/ldaptests/jndi/ops/search/IllegalSearchFilterTest.java
The class contains a test method testFiltersWithSyntaxErrors which expects an InvalidSearchFilterException in case of a filter like "This is no filter" or "blah". It works as expected for RC1, but it seems to me that it is the JNDI provider for LDAP on the client side causing the exception (no ApacheDS involved).

How was the error achieved in detail? What does "try simple malformed filter" exactly means? command line tool like ldapsearch?

ok, the issue is 4 months old, and we asked for more info, but didn't get some.

We may close this issue and reopen it if needed. wdyt ?
