IllegalStateException while compiling EXTERNAL type definition

[rkosegi]

I have following type definition:

XYZ02AccessControl ::= --xyzcc isPdu:"TRUE" -- EXTERNAL

which is causing this error:

Generating classes for module "XYZ02-ASN1"
Exception in thread "main" java.lang.IllegalStateException
	at org.openmuc.jasn1.compiler.BerClassWriter.followAndGetNextTaggedOrUniversalType(BerClassWriter.java:2491)

	at org.openmuc.jasn1.compiler.Compiler.main(Compiler.java:89)

AFAIK this ASN1 file used to be compiled with binary notes compiler without any problems.
How can I make it work with JASN1?

JASN1 compiler version : 1.8.1

Yes, the EXTERNAL type is currently not correctly handled.

But you can avoid the problem by replacing your ASN.1 statement with this:

XYZ02AccessControl ::= MyExternal

MyExternal  ::=  [UNIVERSAL 8] IMPLICIT SEQUENCE
     {
      direct-reference  OBJECT IDENTIFIER OPTIONAL,
      indirect-reference  INTEGER OPTIONAL,
      data-value-descriptor  ObjectDescriptor  OPTIONAL,
      encoding  CHOICE
                  {single-ASN1-type  [0] ANY,
                   octet-aligned     [1] IMPLICIT OCTET STRING,
                   arbitrary         [2] IMPLICIT BIT STRING}
     }
