#1755 CMR Setter throws IllegalStateException

[Andrew Thorn]

I have been getting this quite a lot lately, with JBoss
3.2.4RC1 from CVS (about a month old). The exception is
thrown from the following code:

public void linkExpressionProbesAndAnnotations()
throws AnalysisException {
try {
// Load all of the ExpressionProbe records
and process them so that their one-to-one
// relations with the
ExpressionProbeAnnotation database are correct.
// This could take a long time, and with
CMP, also a lot of memory, unfortunately.
Collection probes =
ExpressionProbeUtil.getLocalHome().findAll();
for (Iterator i = probes.iterator();
i.hasNext();) {
ExpressionProbeLocal probe =
(ExpressionProbeLocal)i.next();
String probeName = probe.getName();
String chipName =
probe.getChipType().getName();
Collection annotations =
ExpressionProbeAnnotationUtil.getLocalHome().findByProbeNameAndChipName(probeName,
chipName);
if (!annotations.isEmpty() &&
annotations.size() > 0) {

probe.setAnnotation((ExpressionProbeAnnotationLocal)annotations.iterator().next());
} else {
log.warn("Empty Annotations!
"+annotations.size());
}
probe = null;
annotations.clear();
}
} catch(Exception e) {
e.printStackTrace();
throw new AnalysisException("Unable to link
expression annotations.", e);
}
}

The line that it is thrown from is the line which
begins 'probe.setAnnotation'. Since there is no
EJBCreate actually ocurring (unless it's somewhere in
the container) -- all I'm doing is finding objects
using a finder -- I think this is a bug in the container.

Thanks.

In JDBCStoreManager, does the following method look like this?
public void activateEntity(EntityEnterpriseContext ctx)
{
activateEntityCommand.execute(ctx);

// looad at the cache for preloaded data
boolean loaded = readAheadCache.load(ctx);

// if there was some preloaded (in this current tx)
data, we can set valid to true
// and avoid executing load command when the instance
is accessed.
if(loaded)
{
ctx.setValid(true);
entityBridge.setCreated(ctx);
}
}

Please, try it with fresh 3.2.4 copy from CVS. Thanks.

I updated my 3.2.4RC1 to the CVS release from today, and the
error can no longer be reproduced. It took me a little while
to adapt to Tomcat 5, but it no longer gives the
IllegalStateException with the same code I mentioned above.

Thanks, Alexey.
