Hey Stefano,

I expect the error to be on my side, your approach looks perfectly fine to me. I'll give it another try and come back to you as soon as I can (presumably tomorrow).

Thanks for efforts, kind regards, Lukas

Hi Lukas,

just to be thorough I tried all the steps I have described in my earlier e-mail on a different workstations running a different OS (linux), and the attempt yielded the same Exception.

Ciao Stefano

Hi Lukas,

Interesting. I have gotten all your maven repository jar files and included them in the class path as follows:

$ echo $GVYCP C:\opt\jlib\basex-api\xmldb-api-1.0.jar;C:\opt\jlib\basex-api\xqj- api-1.0.jar;C:\opt\jlib\basex-api\basex-api-6.1.3.jar;C:\opt\jlib \basex-api\basex-6.1.3.jar

the same but more clearly listed

$ dvcp GVYCP 0) C:\opt\jlib\basex-api\xmldb-api-1.0.jar

1. C:\opt\jlib\basex-api\xqj-api-1.0.jar
2. C:\opt\jlib\basex-api\basex-api-6.1.3.jar
3. C:\opt\jlib\basex-api\basex-6.1.3.jar

I have run the same java class I have enclosed in the earlier version as follows:

$ java -version java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing)

$ java -cp ".;${GVYCP}" NPEReproducer java.lang.ArrayIndexOutOfBoundsException: 5 at org.basex.query.up.Primitives.add(Primitives.java:52) at org.basex.query.up.DBPrimitives.add(DBPrimitives.java:40) at org.basex.query.up.Updates.add(Updates.java:90) at org.basex.query.up.Insert.atomic(Insert.java:102) at org.basex.query.up.Insert.atomic(Insert.java:30) at org.basex.query.expr.Expr.iter(Expr.java:58) at org.basex.query.QueryContext.iter(QueryContext.java:322) at org.basex.query.QueryContext.iter(QueryContext.java:290) at org.basex.api.xqj.BXQDynamicContext.execute(BXQDynamicContext.java: 246) at org .basex .api .xqj.BXQPreparedExpression.executeQuery(BXQPreparedExpression.java: 54) at NPEReproducer.reproduceNPE(NPEReproducer.java:51) at NPEReproducer.main(NPEReproducer.java:60)

I have also checked out your basex trunk and was able to build basex-6.1.3.jar, and even with that jar the same exception was thrown.

I was not able to build the api maven project as it could not resolve the jax-rx dependency.(see attached log)

I was able though to build an api jar from your trunk that contained only the xml:db and XQJ drivers from trunk, and with that too the same exception was thrown.

So I have tried with the jars that I have downloaded from:

http://www.inf.uni-konstanz.de/dbis/basex/maven/org/xmldb/xmldb-api/1.0/xmld... http://www.inf.uni-konstanz.de/dbis/basex/maven/javax/xml/xquery/xqj-api/1.0... http://www.inf.uni-konstanz.de/dbis/basex/maven/org/basex/basex-api/6.1.3/ba... http://www.inf.uni-konstanz.de/dbis/basex/maven/org/basex/basex/6.1.3/basex-...

I have also built basex-6.1.3.jar and basex-6.1.3.jar (w/o jaxrx) from your trunk, and yet I was not able to run it as you were able to do.

Is there anything I am missing?

Ciao Stefano

Hey Stefano,

thanks for your report.

...

I am enclosing a java class file that reproduces this problem against 6.1.3 basex jar files

Unfortunately I wasn't able to reproduce the exception by running your code - neither with version 6.1.3 nor with our current repository version. It runs fine on my machine. Do you have a clue where I could've missed something?

Or - if you have another case at hand where you encounter the same problem, just let us know and we'll see what we can do.

Kind regards, Lukas
