Two tests fail on BoxLang — e.message null for Java exceptions and for (var key in e) incompatible with BoxLang exception objects

[DiscountDarcy]

What are the steps to reproduce this issue?

Run the test suite on BoxLang 1.15+ (box testbox run with cfengine=boxlang).

What happens?

Two tests fail:

1. can log Java exception (SentryTests.cfc:49)

getLogbox().getRootLogger().error( e.message, e );

When catching a Java exception (e.g. java.io.File.init(null)), e.message is null. BoxLang's Logger.error() requires a non-null message argument and throws:Required argument message is missing for function logMessageThis also fails on Lucee 5 — e.message is empty string on Lucee but null on BoxLang, and Logger.error() treats both as "missing" when forwarded via argumentCollection.Fix: e.message ?: "Java exception" (null-safe operator, works on all engines).

2. can log exception with no tagContext (SentryTests.cfc:58-62)

for ( var key in e ) {    if ( key != "TagContext" ) {
        newE[ key ] = e[ key ];
    }
}

BoxLang exception objects don't support key iteration via for (var key in e). The only accessible field is errorCode; accessing other keys throws:The instance [CustomException] has no public field or inner class [...].

The allowed fields are [[errorCode]]

Fix: Replace with duplicate(e) + structDelete(newE, "TagContext"), which works on all engines.

What were you expecting to happen?

Both tests should pass on all supported engines (Lucee, Adobe ColdFusion, BoxLang).

What versions are you using?

Operating System: Ubuntu 24.04
Package Version: 2.1.6
CF Engine: BoxLang 1.15.0, Lucee 5.4.8
