JVM process crash in net.sf.jasperreports.engine.export.JRGridLayout.horizontallyMergeEmptyCells

[amasson]

 I have a JVM crash during a JasperReport generation.

After searching the Oracle Java bug database, it seems that I'm not the only one to have this problem:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7177085

It's exactly the same problem.

 

I know it's not a bug in JasperReport lib itself,

but was this bug observed by others ?

and is there a known workaround to avoid it?

(A full Tomcat crash has some serious consequences...)

 

I cannot provide a sample code, just some info:

- it occurs with JR 4.5.0 (in Tomcat 7) on a Linux with  a 64-bit JVM, JDK 1.7.0u3/DK 1.7.0u5.

- the report must be generated several times (probably to trigger the JIT compiler)

- seems to not occur on Windows, only on Linux

 

Thanks in advance!

 I have founds this workaround. This option must be added to the JVM command line:

    -XX:CompileCommand=exclude,net/sf/jasperreports/engine/export/JRGridLayout,horizontallyMergeEmptyCells

I have the same issue with Jasper Reports 4.7.1 on JDK 1.7.0_09 on Windows 7 64-bit.

Adding -XX:CompileCommand=exclude,net/sf/jasperreports/engine/export/JRGridLayout,horizontallyMergeEmptyCell to the JVM did not resolve the issue.

Seems for large HTML reports I experienced this bug as well, below is some info:

Investigating this lead me here: http://stackoverflow.com/questions/13912090/a-fatal-error-has-been-detected-by-the-java-runtime-environment-sigsegv-0xb-a and here: http://java.dzone.com/articles/dont-use-java-7-are-you

 

Adding the below JVM option worked for me:

 

 -XX:-UseLoopPredicate -XX:-LoopLimitCheck

 

This option did not work:  -XX:CompileCommand=exclude,net/sf/jasperreports/engine/export/JRGridLayout,horizontallyMergeEmptyCell

Thanks djkrite - adding

 -XX:-UseLoopPredicate -XX:-LoopLimitCheck

to the JVM worked for me too (Jasper v3.7.4, Java 1.6.0_36)
