Matt Pavlovich updated OPENJPA-2690:
------------------------------------
Description:
When openjpa is running in an OSGi environment and all packages not being
imported properly may result in the oracleClob_empty_lob_Method being set to
null, a NPE will occur when trying to persist an entity with a NULL CLOB column.
getEmptyClob() (and probably getEmtpyBlob as well) should detect for
oracleClob_empty_lob_Method being set to NULL before attempting to invoke the
method, or just return the EMPTY_CLOB constant.
{noformat}
private Clob getEmptyClob()
throws SQLException {
if (EMPTY_CLOB != null)
return EMPTY_CLOB;
try {
return EMPTY_CLOB = (Clob) oracleClob_empty_lob_Method.invoke(null,
new Object[0]);
} catch (Exception e) {
throw new SQLException(e.getMessage());
}
}
{noformat}
Reference:
During constructor of OracleDictionry.. this may return null:
{noformat}
private Method getMethodByReflection(String className, String methodName,
Class<?>... paramTypes) {
try {
return Class.forName(className,true,
AccessController.doPrivileged(J2DoPrivHelper
.getContextClassLoaderAction())).
getMethod(methodName, paramTypes);
}
catch (Exception e) {
// all fine
}
return null;
}
{noformat}
