com.sun.jdi.InvocationException occurred invoking method
Hi list,
while walking through the code with debugger (eclipse juno) I get the following:
com.sun.jdi.InvocationException occurred invoking method.
This is while trying to see org.apache.lucene.search.ScoreDoc
So the debugger seams to have a problem with the toString() of ScoreDoc.java
which looks as follows:
// A convenience method for debugging.
@Override
public String toString() {
return "doc=" + doc + " score=" + score + " shardIndex=" + shardIndex;
}
I have no problems with toString() from other classes so the solution might be
to first create a String and return the String value?
// A convenience method for debugging.
@Override
public String toString() {
String s = "doc=" + doc + " score=" + score + " shardIndex=" + shardIndex;
return s;
}
Or use a StringBuilder like in org.apache.lucene.search.Sort.toString()?
Any thoughts on this?
Regards
Bernd

OK, so the solution will be that ScoreDoc.toString() should return
a local string with "return s;", right?

While inspecting the content of topDocs.ScoreDoc I see 4 variables:
- doc
- fields
- score
- shardIndex
But ScoreDoc knows only about 3 (doc, score, shardIndex) is this the problem?

I have no idea how eclipse's debugger is implemented. But please
report the bug to them.
if their debugger works for 'z = x + y; return z' but not for 'return
x + y', then its broken!

Are you sure that this is a bug in eclipse?
When using a local string and then returning the string the error is gone
and the content of the class displayed.
AFAIK eclipse is just an ide and using the java debugger, so this is then a java debugger problem?

you should report the bug to eclipse. This is a bug in their debugger,
not an issue with lucene.
