Subject [jira] Resolved: (DERBY-1315) Statement optimization/compilation fails with OutOfMemoryException in largeCodeGen test with embedded and framework DerbyNetClient
Date Wed, 06 Sep 2006 21:44:24 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1315?page=all ]

A B resolved DERBY-1315.
------------------------

    Fix Version/s: 10.2.2.0
                       (was: 10.2.1.0)
       Resolution: Fixed

A fix for this issue has been checked into 10.3 and ported to 10.2 (thanks Dan and Rick).
 The remaining work is to update largeCodeGen to run with 10,000 unions and to investigate
related issues.  I''ve filed DERBY-1818 for tracking of that test work and am thus resolving
this issue.

> The test case lang/largeCodeGen.java was run as is without giving any -Djvmflags="-mx512M
-ms512M" and gave the following error:

> Then the test case lang/largeCodeGen.java was run with -Djvmflags="-mx512M -ms512M",
and it gave the following error:

> Then I modified test case lang/largeCodeGen.java to set PRINT_FAILURE_EXCEPTION  to true
and ran the test again. This time I got the following error and stack trace:
