Do you have any releases of this component after this one was fixed?
> DAS CommandImpl(String) leaks EMF/XSD XSDImportImpl objects for sdoModel.xsd
> ----------------------------------------------------------------------------
>
> Key: TUSCANY-1872
> URL: https://issues.apache.org/jira/browse/TUSCANY-1872
> Project: Tuscany
> Issue Type: Bug
> Components: Java DAS RDB
> Affects Versions: Java-DAS-Next
> Reporter: Ron Gavlin
> Assignee: Luciano Resende
> Priority: Critical
> Fix For: Java-DAS-Next
>
>
> Whenever a DAS rdb.impl.CommandImpl is constructed, it attempts to re-load
> the schema definition for the "commonj.sdo/java" namespace which imports the
> "commonj.sdo" namespace. For each XSDHelper.define() invocation, an new
> XSDImportImpl is allocated which contains its own XSDSchemaImpl object for
> the "commonj.sdo" namespace which is 25K in size. Many constructions of the
> DAS rdb.impl.CommandImpl will eventually cause an OutOfMemoryException.
> Tuscany SDO already pre-defines the "commonj.sdo/java" namespace as part of
> its initialization. According to JIRA issue TUSCANY-20, this used to not be
> the case. Now that TUSCANY-20 is fixed, the DAS should no longer be
> attempting to define the "commonj.sdo/java" types.
> The patch below removes these lines of code which are causing the memory
> leak. Please apply ASAP.
> Thanks,
> - Ron
