Closed Issues in 5.15.1_HF-004 (This Release)

BW-21439
Licensing Activation support added through this release of TIBCO BusinessWorks 5.15.1 Hotfix 4.

BW-20070
Added a new property to suppress the Accept-Encoding header in the SOAP Request Reply activity without affecting the decompression behavior of the Send HTTP Request activity.
This is a property based solution.
The name of the property is " bw.plugin.soap.decompressGzipResponse ".
# Keep HTTP compression enabled (Default)
java.property.bw.plugin.http.decompressGzipResponse=true
# Disable SOAP compression to avoid ZLIB errors
java.property.bw.plugin.soap.decompressGzipResponse=false
Set the property to false to disable the addition of the accept-encoding header. Default value is true.

BW-20360
Fixed an issue where SOAP activities utilizing Web Service Security (WSS) failed to process requests correctly.
TIBCOwss4j.jar has been upgraded to 1.6.404.002 to have compatibility with Xmlsec-2.3.0.jar

BW-20385
Support for SSL has been added for the TCP palette.

BW-20386
A fix has been implemented to resolve an issue where the Get Shared Variable activity would get stuck inside critical section groups when using MS SQL Server as the engine database.
This update introduces a property-based fix to address the issue. You can now use the property "bw.engine.sharedLockConfigName"=<Shared lock name>, where the name of the shared lock resource should be specified. This property should only be configured when the Get Shared Variable activity is used within a critical section group and execution becomes stuck.

BW-20539
Fixed the SOAP Event Source to populate Signature/Value with the request message signature instead of the signing certificate signature.

BW-21070
Trace context propagation not working in SOAP/JMS scenario with multiple invocations.

BW-20807
Updated the OpenTelemetry Tracing property with this HF04 release.
New property is bw.engine.opentelemetry.traces.enable
User can set this to "true" to enable Opentelemetry tracing.
