Improvements
Performance improvements
The Java agent now starts up to 50% faster. Your applications will be available that much sooner.
Fixes
- In some cases JAX-RS annotations on interfaces were not being observed, causing transactions using JAX-RS services to be named on the servlet rather than the web servicepath and method.
- Fixed an issue that prevents Spray and Akka-HTTP instrumentation from applying when using Scala 2.10.
- Fixed an issue that caused Play 2.x requests to produce empty responses when the circuit breaker is tripped.
- Fixed an issue where setting
enable_custom_tracingtofalsecould inadvertently disable Netty instrumentation.
Known Issues
Fixed in 3.29.0
- Applications that use Play and Ning AsyncHttpClient may miss transactions.
- The thread profiler may not report data while profiling certain Scala classes.
Fixed in 3.28.0
- Fixed a bug that could cause Akka Http instrumentation to throw a
NullPointerExceptioninto customer code.
- Fixed a bug that could cause Akka Http instrumentation to throw a
Fixed in 3.27.0
- Fixed an issue where the agent treated HTTP headers as being case sensitive, causing CAT to miss under certain conditions.
- Fixed various issues related to the proper handling of multibyte character encoding.
Fixed in 3.26.x
- CXF instrumentation can name transactions based on auto-generated proxy classes. Later agents now normalizes CXF transaction names.
- EJB instrumentation may cause a
NullPointerExceptionin application code, and erroneously set transaction names. In later versions, the agent records a metric. - The Cross Application Tracing API caused Application Response time to be attributed to other transaction time, and prevented linking of transaction traces when doing CAT.
- Request queuing calculations could show queuing time as a steadily increasing value instead of the correct time.
- HttpURLConnection External metrics may not report on the IBM J9 JVM.
- Transaction traces may report external segments for non I/O calls in Apache HttpClient.
- The Java agent will now read Cross Application Tracing HTTP header names regardless of case.
- Fixed a bug that could cause cross application tracing between the New Relic Java agent and non-Java New Relic agents to fail.
