Report Hangs App on Object.wait()

[timkuntz]

I have a report with subreport(s) that hangs my application when certain data conditions occur. The hang is due to the following call to Object.wait() in the JRThreadSubReportRunner.waitResult method.

 

--- code snippet ---

// waiting for the subreport fill thread to fill the current page

subreportFiller.wait();

// FIXME maybe this is useless since you cannot enter

// the synchornized bloc if the subreport filler hasn't

// finished the page and passed to the wait state.

--- code snippet ---

 

The FIXME in the code hinted at being able to remove the wait... which I did... which fixes the problem! Does anyone know if I'm setting myself up for other problems by doing so?

 

Thanks,

Tim

I'm a fool.

 

With a little more testing I realized that it solves that hang but the sub-reports are not being rendered - don't ask how I missed that!

 

Has anyone else run into issues with that code and come up with a solution?

Hi,

 

What version of JasperReports are you using?

Could you post some files here in the form of a sample that would help us to reproduce the problem?

 

Thank you,

Teodor
