JVM crash

2003-05-16 00:33

hello,

 

I'm using JasperReports 4.5 with windows 2000 SP2 and a jdk4.1 and I'm faced with jvm crash. The message of the crash is the following:

 

Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x6D3CE26A

Function=JVM_FindSignal+0x17C1C

Library=X:j2sdk1.4.1_01jrebinclientjvm.dll

Good bye.

Java Result: 1

 

This problem happens randomly. I've tried others jdk version (1.4.1_01 and 1.4.1_02) but the problem still persist. Is it a bug of JasperReports. If anybody can help me, I will appreciate.

 

thanks,

Jeremy

I've posted a similar question to the support mailing list, but without any response.

 

https://sourceforge.net/tracker/index.php?func=detail&aid=702128&group_id=36382&atid=416704

 

Does anyone has an idea?

I've encountered this problem before, but only when I use jdk 1.4.2 beta.

 

As soon as I remove 1.4.2 beta and reinstall 1.4.1_02, there is no such error.

 

To be sure, have tested it time - remove/install between 1.4.2 beta and 1.4.1_02 stable - this problem always occur on 1.4.2 beta jvm.

 

I'm using JasperReports 0.4.6.

I 've never installed jdk 1.4.2 beta on my computer, and the problem happens randomly with the jdk 1.4.1_02. If anyone has another suggestion, it would help.

 

thanks,

Jeremy

Yep I got this too, using jdk 1.4.1_02

I got the same error using JDK 1.4.0 and JDK 1.4.1_02. For me, the problem appears when I call:

 

JasperPrint pr = JasperFillManager.fillReport(JasperReport,Map,DataSource);

 

three or four time with the same report object, but a different Datasource. Anybody have any idea what to do? This puppy is a real show stopper.

Hi,

 

I've managed to solve my JVM crash issue. However, it may not apply to all related JVM crashes, as mine specifically crashed 1.4.2 (both beta and the official release) but not 1.4.1 (all sub version 02,03 is ok too).

 

In summary, my JVM crashed was due to my code calling System.gc() too often (after printing each report, trying to free resources asap).

 

For my case, when the JVM crashed, it does not show a Library reference on the crash message. But it does show some common messages, such as :

 

..

Good bye.

at dori.jasper.engine.fill.JRCalculator.evaluate(JRCalculator.java:678)

 

As soon as I remove the code calling System.gc(), the 1.4.2 JVM performs solidly - without a single JVM crash. But it does show at least one 'out of memory' instance during my stress test, which probably won't happen in real use (I hope).

 

If your code calls System.gc() at all, try removing it and see if it helps.

 

Anyway, 1.4.2 handles gc internally better than 1.4.1, so I don't really need to call it manually, but still funny, calling gc can crash the JVM.

I think I may have found the solution to the problem.

 

In the methods dori.jasper.engine.fill.JRCalculator:

 

evaluate(JRExpression expression) and

evaluateEstimated(JRExpression expression)

evaluateOld(JRExpression expression)

 

The code looked like this (with slight variations for each method)

 

try {

value = this.evaluate(expression.getId());

}

catch (NullPointerException e){}

catch (Exception e) {

throw new JRException("Error evaluating expression value : " + expression.getName(), e);

}

 

I changed it to

 

try {

if (expression != null)

value = this.evaluate(expression.getId());

}

catch (Exception e) {

throw new JRException("Error evaluating expression value : " + expression.getName(), e);

}

 

and it stopped blowing up. I think it might be that too many exceptions being thrown (expression appears to be null quite a lot of times in each fill) and too many stack traces are causing the VM to wig out.

 

Is it possible to get this fix into the next release of Jasper Reports?

Hi,

 

Try to launch your JVM using the -server command line

switch instead of the default which is -client.

 

Thank you,
