Domino classic Java elements encoding problems

Recently I encountered a problem, where Notes Java agent contained strange characters. My Domino Designer was set to UTF-8 and everything looked fine when I changed those characters to correct ones, but only until I reopened this design element again.

I tried to reproduce the issue in different VM, but the problem didn't occur and since I have never seen it before, I started to blame Windows 8 for that, since other VM was Windows 2003 and both were English versions with default region for non-Unicode programs set to Czech.

Only option I had was to switch back to non-Eclipse editors, but when I tried to open the element, it looked even worse.

For example this code (check the line with a comment):
When reopened:

When reopened in classic editor:
This can get really bad when such characters occur in string constants.

Only solution was to fix the element in classic editor and leave it this way. Not really good for development.

Today, I was testing the agent again and when I decided to try to print the code to console, the output wasn't correct either (which was just fine in old VM).

Hopefully this lead me to the solution. When you hit 'p' in Java console, you can get some basic information about the environment. And to my surprise it mentioned file.encoding=Cp1252, which is default for English windows, but I really want to deal with UTF-8 only.

To change this option, you can set this option on JVM startup, or use environment variable JAVA_TOOL_OPTIONS. I didn't want to experiment with eclipse.ini for Notes client, so I just created environment variable JAVA_TOOL_OPTIONS : -Dfile.encoding=UTF8


After I restarted my Notes client everything seems to work just fine. Console outputs all characters and I'm able to edit same code from both old and Eclipse based editors. Also non-binary export to ODP seems to contain valid UTF-8 version of the code.

I'm not sure if this setting can break something else, but I really try to default encoding to UTF-8, so I'm willing take the risk.

XPages Date Field Issue: Solving the One-Day Jump on Every Save

 A user reported a very strange issue - when a document with a date field is saved, it changes the value one day to the past. With every save. But only for some dates, not all. It turned out to be a mystery that goes deep into XPages and Notes/Java APIs. I've posted a sample on OpenNTF Discord and Serdar tried it on his server - no issue. But he uses the GMT zone and I have CET (Windows set to UTC+1 - Amsterdam, Berlin... to be precise). To cut it short, the issue is caused by daylight saving interpretation between Notes and Java. The date fields (because XPages have no notion of real date-only fields) are stored with 00:00 time component and for some dates the conversion back to Java Date resulted in 23:00 on the previous day. XPages that get the date component as String for the input field, which is then saved back as a previous day during document save. The app is full of date fields and I couldn't add custom logic to every save operation, so I tried to fix it at XPages conv...

HCL Domino 12.0.2, Engage 2022 and HCL Factory tour Milan

 I haven't published my recap after Engage this year and the recent HCL Factory tour in Milan is a great opportunity to write a summary about what's happening in HCL (mostly Domino) space. It's a mix of news about 12.0.2, future directions, and my impressions, so it can be a bit chaotic, but I got the impression that many people see it similarly.  Engage 2022 Engage 2022 was great (as always). I love the atmosphere in Brudges. I visited it once after Engage a few years ago and I was happy to come back. This was also the first time I had the opportunity to speak at Engage, which obviously made it a bit more stressful, but also more fun. Together with Domino Jams, HCL continued conversations with customers and partners about the future of their products at Engage. Many of these ideas were now discussed in greater detail in Milan, some of them were even demoed.  My main takeaways from Engage were: Nomad (web and mobile) are a great addition to Notes family Restyle is a great...

XPages EL/class-loader memory leak (now with solution)

 We have recently experienced OutOfMemory crashes of XPages app server. The server was recently upgraded to 12.0.1FP1, but we were getting some panic crashes in HTTP even before the upgrade (it was 9.0.1FP10). Our hopes were that the upgrade would stabilize the server, but it's not the case. At least now I start to see what's the problem.  update 8.12.2022 There were actually 3 different leaks. I have rewritten the article to be a bit more clear. I also re-run some of the tests on 9.0.1FP10, so I assume the problems are also in earlier versions. Problem 1 The server is hosting over 1000 NSF sharing the same design + some other custom apps. Not all NSFs are used via web as the app still has classic Notes UI in parallel, so it's a bit tricky to estimate the load. By using tell http xsp show modules I usually see around 350 NSFs active. We kept the default application timeout that should provide reasonable application recycling if it's not used continuously.  We started to...
