BTrace 2.2.6 has been released (github.com/btraceio/btrac…) It is a minor bugfix release

I have been silent for long time here. The reason was a rather difficult task of revamping the indy linking such that half of JDK does not need to be excluded from instrumentation in JDKs after 17. Well, I have good news - there is a progress there and I’m moving towards 2.3.0

BTrace 2.2.3 has been released (github.com/btraceio/btrac…) just in time for Christmas. Enjoy the bundle of various bug fixes and improvements collected over this year.

BTrace 2.2.2 maintenance release A bunch of rather minor updates. Works on #Java18 (woohoo) Available on GitHub (github.com/btraceio/btrac…), Maven Central and SDKMan (sdkman.io)

Considering your first contribution to BTrace? Here is a good opportunity if you happen to have access to Windows 11 - github.com/btraceio/btrac…

GitHub discussions have been set up for BTrace - feel free to start using it to discuss anything BTrace related. github.com/btraceio/btrac… Also, a reminder that there is Slack workspace you can join as well - join.slack.com/t/btraceworksp…

BTrace 2.2.1 is out. A minor bugfix release - see github.com/btraceio/btrac… for the details about the bugfixes. As usual, available via @sdkman_ ('sdk install btrace 2.2.1') and on Maven central.

BTrace support in @VisualVM 2.1 updated to the latest version! #java #performance #visualvm #bytecode

"#JFR has some interesting challenges ahead. Some of them will be compounded by the introduction of Virtual Threads in #Java," explains @hirt from @datadoghq in a detailed assessment on Foojay.io Today: foojay.io/today/openjdk-… #foojaytip

"BlockHound transparently instruments #Java classes and intercepts blocking calls (e.g., IO) if they are performed from threads marked as non-blocking operations only." What, how? @nicolas_frankel from @hazelcast explains it all: foojay.io/today/blockhou…

Also, anyone out there using the BTrace Services API?

Is there any interest in being able to use @opentelemetry APIs from BTrace? Asking for a friend ... (please, RT)

And the artifacts are in sonatype repo and should hopefully be synced to maven central shortly.

BTrace 2.2.0 has been released - No binaries deployed to @bintray - Maven artifacts deployed directly maven central via @sonatype_ossrh - Available at @sdkman_ - Fixed JDK 16 support in the CLI client - Various issues fixed github.com/btraceio/btrac…

Have been playing with invoke dynamic to prototype a simple extension system for @btraceio - seems rather promising. With its help it should be possible to bring 'modern' tech like @opentelemetry for BTrace script authors to use. Still a long way to go, though.

@alblue True. But quite surprisingly it was not uncommon to see that in use as recently as last year. The ASM 9 is the last straw - it was nigh impossible to test against JDK 7 anyway thanks to difficult accessibility to the binary builds.

This is an early warning - since version 2.2.0 BTrace will drop support for Java 7. In order to support the upcoming Java 16, BTrace needs to use ASM 9.0 which is Java 8 only compatible.

New #btrace 2.1.0 has been released (github.com/btraceio/btrac…) - JFR support with custom events definable in the BTrace probe (tinyurl.com/yyt56d95) - support for unattended execution (tinyurl.com/yxg9gobo) #java #btrace #bytecode #performance #jfr #profiling

Are there any active users of @visualvm plugin for @btraceio integration? Have been trying to update a rather prehistoric version to something more up to date last 2 days and I am beginning to wonder whether this even makes sense. Plz, retweet and like if interested in plugin.
