[Quickfixj-users] Using multiple versions of FIX with Quickfix

[Attila-Mihaly B. <dif...@gm...>]

Hello,

I'm trying to use QuickFix to implement an exchange simulator which accepts
sessions using multiple FIX versions (4.0, 4.1, etc).

I build QuickFix from the Gihub sources using: mvn install

I add a dependency on it using:

<dependency>
            <groupId>org.quickfixj</groupId>
            <artifactId>quickfixj-all</artifactId>
            <version>1.6.0-SNAPSHOT</version>
</dependency>

However when I try to run it, it fails with the following error message:

java.lang.VerifyError: Bad type on operand stack
Exception Details:
  Location:

quickfix/fix41/NewOrderSingle.<init>(Lquickfix/field/ClOrdID;Lquickfix/field/HandlInst;Lquickfix/field/Symbol;Lquickfix/field/Side;Lquickfix/field/OrdType;)V

at quickfix.MessageUtils.parse(MessageUtils.java:112)

>From what I understand this is because HandlInst is a subclass of
StringField in FIX41 but it's a subclass of CharField in later versions.
During compilation of the library the first one is used (hence the setField
calls in quickfix/fix41/NewOrderSingle refer to setField(StringField)), but
in the actual jar we have HandlInst derived from CharField, thus making the
class loading fail.

Any idea how this should be resolved? Has anyone used QuickFixJ with
multiple FIX versions in parallel in the same application?

Thank you,
