[#3694] - EmptyStackException in OLAP Analysis in JasperServer 5.6

I am also getting this same error with JasperServer 5.6. I just upgraded from 5.0.

Able to work around this bug by applying a patch to mondrian. The problem appears to be in the way ji-jpivot-5.1.0 uses mondrian but the source for ji-jpivot does not seem to be available. Instead I patched mondrian. Started with mondrian version 3.6.7 (tag = 3.6.7-R) and applied the following patch. The resulting jar was hot-patched into our production JasperReports Server 5.6.0. Obviously it is not a great fix but it got our Analysis working again.

There are other registrations for this problem in #4005 and #4038. Does anybody have a workaround other than the one above? Nothing I've tried works. Either the build fails, or the Tomcat start up fails.

Version 6.01.
The bug is still there.

Long-standing critical error.

Is it possible to have at least an answer if this problem will be solved someday?

I can´t upgrade the version because of this problem!!!

Got It!

On 6.1.1 in JbossAS 7.1.1final..

1- Read the correct release of Mondrian from the file VERSION.TXT in mondrian-3.6.4-JS-1.jar (open with rar / 7z ..ecc. This name is correct for 6.1.1 for 6.2.2 is different but quite similar).

here's the content of Version File.

Title: mondrian
Version: 3.6.4
VersionMajor: 3
VersionMinor: 640
Vendor: Pentaho

2- download it form github -> https://github.com/pentaho/mondrian/releases

3- Import the prject under Eclipse

4- Modify the file as ddaly says:

public List<Member> getMemberChildren(Member member) {
- return schemaReader.getMemberChildren(member);
+ try {
+ return schemaReader.getMemberChildren(member);
+ } catch (java.util.EmptyStackException e) {
+ return schemaReader.withLocus().getMemberChildren(member);
+ }
}

5-compile your project and rename the jar with the correct name.

6-turn off your server and overwrite the old file (or place it in another folder --> not in jasperserver.war or subfolder)

7-Turn on your server.

Now you can expand dimension and filter in in the CUBE settings without getting errors.

P.s.: you can overwrite the DelegatingSchemaReader.class file in your jar...

thanks again ddaly.
Paolo.

does anyone have any news on this bug.
thank's

I was so frustrated that I've finaly compiled modrian library with fix proposed by pmaffeis, now problem does not exist (I hope there is only critical error in 6.2)
Mondrian jar:

The file provided by Dyrex doesn't work for parent child hierarchies; the same thing needs to be done to schemaReader.isDrillable(member) too. Here's the compiled jar file with that addition https://drive.google.com/open?id=0B01Lyhhy36jeMlN6RGZCNUl0T0k

I've overwritten the mondrian-3.6.4-JS-1.jar file with the one patching by the user servantofchristjesus in Jasperserver 6.3.0 but it doesn't work. The problem with CUBES is still present.

Yeah!! Thanks!!!

In version 7.5 is not fix too, but with patch it's work. Many thanks.
