I do often got this crash, while using ResultSetDataSource.

Mine also very similar to this. i.e. the exception is started at dori.jasper.engine.fill.JRCalculator.evaluate(JRCalculator.java:707)

Please help us to resolving this issue. Thanks for your help.

Navaneethan.

The problem here is that probably two or more users are executing the same report at the same time. Every Jasper report will be compiled into a java class before it gets executed. This process must be synchronized between Threads or else the JVM might crash like in your description because two threads may write into the same class file at the same time.

I traced the code and it seems to happen in one of the evaluate(JRExpression expression ) methods in JRCalculator.java

I fixed it temporarily by adding a e.printStackTrace() in the catch Null pointer exception so that when my report gets into this state, it doesnt crash our web server.

Hi,

I have the same issue. My env is single user, standalone Java application generating automated reports. As a temporary fix I use

java -Xmx200m xxx.yyy.zzz

This works erratically. Sometimes I am able to get the entire result.


The following is the error msg :

Unexpected Signal : 11 occurred at PC=0x402B0741
Function=(null)+0x402B0741
Library=/usr/java/j2sdk1.4.2/jre/lib/i386/client/libjvm.so

NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.

Hi,

Try to launch your JVM using the -server command line
switch instead of the default which is -client.

Thank you,
Teodor
