Guided rule with DSL is not able to build (ERR102) on ibm16

Description of problem:
Our project which we use for testing is not able to build on ibm 16. It brokes all test scenarios. Build failed with:

but this rule (guvnor/model/cheese) is valid.

Same rule makes problem in other jdk (open, sun) but problem is quite different. Validation fails with same error but build success.

Unfortunately, we are not able to reproduce this issue outside this project.

Version-Release number of selected component (if applicable):
6.0.1 ER2 BPMS

How reproducible:
ibm16 SR6 (IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux amd64-64 jvmxa6460sr6-20090923_42924 (JIT enabled, AOT enabled) )

Steps to Reproduce (ibm16):
1. clone repository to bussines-central (mention in comment 1)
2. go to Project Authoring
4. show Project Editor for project "guvnor"
5. build this project
6. show and validate corrupt rule

Actual results:
Step 5: Build failed with error which was mention in description.
Step 6: Validation success.

Expected results:
If validation is successful then build should be successful too.

Additional info:
affected rule is in package (guvnor/model/cheese)
