Kathey Marsden updated DERBY-177:
---------------------------------
Derby Categories: [High Value Fix]
> Unnecessary waiting within EmbedDatabaseMetaData.getIndexInfo()
> ---------------------------------------------------------------
>
> Key: DERBY-177
> URL: https://issues.apache.org/jira/browse/DERBY-177
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.0.2.2
> Environment: Windows XP, JDK 1.4.2_07, derby embedded server
> Reporter: Jörg von Frantzius
> Attachments: tablelock.diff, testhang.diff
>
>
> When setting up a new schema (creating tables, constraints and indexes),
> using a JDO implementation's autocreate feature (JPOX JDO), the application
> hangs for 20 seconds in a call to EmbedDatabaseMetaData.getIndexInfo(). The
> stacktrace is:
