Error description

  • Exporting a ruleset from Rule Designer fails when the throws
clause of the BOM method declaration contains
EngineInvalidStateException.

For example, the export ruleset of the attached sample fails
because the BOM has the following method definition:
public void addToMessages(string arg)throws
com.ibm.rules.engine.util.EngineInvalidStateException;


The following stackstrace can be found in the log:

!SUBENTRY 1 com.ibm.rules.studio.rve 4 0 2019-07-24 14:31:12.281
!MESSAGE B2X migration failed. See console error output for
