Informix - Problem description

Problem IT34887 Status: Closed

ASSERT CALLING MT_LOCK_HELPER FROM SAPI_DRAIN_MEM AFTER CALLING JAVA UDR
THAT RETURNS JAVA.UTIL.VECTOR AS LIST(VARCHAR NOTNULL)

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
This problem reproduces running 12.10.FC14 on linux x86-64 but
it's suspected not to be platform specfici.

The key pieces to this repro seem to be

Call a stored procedure from database1.

This procedure calls a stored procedure from database2.   The
stored procedure in
database2 calls a java UDR that returns a Vector type
(java.util.Vector) into a LIST(LVARCHAR NOT NULL)
as this function definition shows:

CREATE FUNCTION satoriaddress(CHAR(64), CHAR(64), CHAR(64),
CHAR(64), CHAR(10), CHAR(10), CHAR(100), CHAR(100))
        RETURNS LIST(LVARCHAR NOT NULL)
        with (class="jvp")
        EXTERNAL NAME 'informix.getlist_jar:getlist.getlist()'
        LANGUAGE java;

After the session completes and the database1 is closed, you
will first see the following assertion possibly followed
by several other varying assertions that may even crash the
server, but this is always the first:

0x0000000001410459 (oninit) afstack
