Oracle has largely been a good steward of #Java. The CentOSization of Java has been complex, and sure, there have been some Oraclisms, But the Java ecosystem is as healthy as it has ever been. Part of the angst around Java over the last few years has simply been people groaning about change, but ultimately the modularization that came in 9, and the "rapid" release cycle is goin…

ok, I am now analyzing dump. customer is on #java 8 181. That's pretty old. I'm not sure those are really changelogs I want to wade into, but I guess I will. Does that version jump out to anyone regarding performance?

is there a jar for the #eclipse Memory Analyzer (aka #MAT)? I can't get .apps to open on my work mac, but I can open jars from the command line.
I attempted to edit the ini file in the .app, but that did not resolve the issue.

How many times would you expect a full gc in a 7 hour window? #java
-
I see some gc-related entries in a thread dump I was given. Is it possible to see how long a gc takes from a thread dump or do we need a heap dump for that? #java

Any #java heads able to help here? My java is pretty limited. There has been work in the UpgradeProtocol method recently. This is the code that upgrades http 1.1 connections to http2 connections in #ApacheTomcat. I am trying to test a fix in stream handling, but I can't get the application to work. :/ ``` [root@pg-master 09:54:57 embed]# java -jar target/tomcat-9-embedded-1.0.…

@musicman Here's a #Java language thought. In general, many of the complexity and boilerplate issues associated with the language could be worked around, but one issue cannot: The language is owned and controlled by Oracle. It may be a fruitful field for several more years, but eventually, ORCL will extract every possible drop of profit out of the language and its ecosystem, ba…

#OSGi: modularity for #Java https://nu.federati.net/url/276851 [www infoworld com]
That article is from 2020. The next one is from 2011. https://www.infoworld.com/article/2074032/osgi---are-we-there-yet-.html

installing #Java 15 for the first time

I figured out I was looking in the wrong place for the hbase stuff. It was in org.apache.hbase. #java is so weird.

how does one determine what version of #SpringSecurity? #java
-
Apparently #Tomcat can give a 404 if you have the wrong version of #Java
...because that makes sense.

well, "enterprise" is largely a bad word in the startup space, to be equated with slow and/or complicated. I am having a related argument about Java. Maybe it is true that the Java ecosystem is too complicated. I was just yesterday unable to get something to work in IntelliJ and I have no idea why. It works in #Eclipse. In any case, I think the Java-naysayers probably don't kno…

I know @pete ...but I didn't when we fediverse met. There have been a few others that have come and gone over the years, but mostly just twitter refugees that went back when they figured out the fail whale (which I think was them moving to #Java). @edythemighty and @marxistvegan are probably the two I spent the most time talking to here, but again, neither of them did I know IR…

I am thinking about writing a #cycling training app for a conference talk, but not sure how exactly it fits into the conference tracks. It could maybe fit in learning a new language, but if it's like "zero to app" in 3 months or something, I don't know how useful it will be. I mean, I have other stuff to do, but largely right now I am being paid to learn #Java (and Java toolin…

thinking about writing a #cycling training app, but not sure how exactly it fits into any of these.

I mean, I have other stuff to do, but largely right now I am being paid to learn #Java (and Java tooling). Interestingly, 12 weeks is what …

@musicman Not an answer, because I don't know, but look into #Java and time zones. I'd guess it probably has its own implementation of the Olsen #timezone database.
