Dataimport of CLOB fields fails when getCharacterStream() is defined in a
superclass
------------------------------------------------------------------------------------
Key: SOLR-1794
URL: https://issues.apache.org/jira/browse/SOLR-1794
Project: Solr
Issue Type: Bug
Components: contrib - DataImportHandler
Affects Versions: 1.4
Environment: Oracle WebLogic 10.3.2
Reporter: Gunnar Gauslaa Bergem
When running Solr on WebLogic application server 10.3.2, the dataimport for
CLOB fields are failing. Line 109 in FieldReaderDataSource.java illustrates the
problem:
Method m = clob.getClass().getDeclaredMethod("getCharacterStream");
Since getDeclaredMethod instead of getMethod is used, the getCharacterStream()
method will not be found if it is defined in a superclass of clob. This is
exactly what
happens in e.g. WebLogic 10.3.2, since the object returned is a dynamically
created wrapper class called Clob_oracle_sql_CLOB. This class does not define
getCharacterStream(), but it inherits from another class that does. This
problem will also occur in other places where getDeclaredMethod used in
conjunction with the CLOB
or BLOB datatypes.
