Random restarts on arm-machine

[sam]

I installed the i2p-router (0.9.38-0) on an odroid xu4 (armv7, ubuntu 18.04) and compiled the wrapper from source as described on the i2p-homepage.

i2p version:    0.9.38-0
Java version:	Oracle Corporation 1.8.0_191 (Java(TM) SE Runtime Environment 1.8.0_191-b12)
Wrapper version:3.5.36
Server version:	9.2.25.v20180606
Servlet version:Jasper JSP 2.3 Engine
JSTL version:	standard-taglib 1.2.0
Platform:	Linux arm 4.14.87-153
Processor:	(armcortexa7)
JBigI status:	Locally optimized library libjbigi-linux-armv7.so loaded from file
GMP version:	6.0.0
JBigI version:	3

Now i got some random restarts after some errors which are:

Please try Java 11 first. 8 is crashy on ARM. I am running several HC1, nearly identical to XU4, successfully with 11. See #2368.

Ok thanks. I just installed the package openjdk-11-jre on ubuntu. Unlike the name suggests this command installs Java 10. I try to find a java 11 build for arm but could not find anything on ​OpenJDK and ​Oracle Java. The Source-Code of OpenJDK 11.0.2 says that is it not recommend to complile it on arm. You should cross-compile it instead. This is to heavy for me. :)

So if you have any source of Java 11 for arm pls let me know.

In the meantime i go on testing Java 10. It now runs several ours without any problems.
To be sure that it works stable i will test it some more days.

By the way: If it works it would be nice to add this info to the router-console for all arm-users.

[jogger]

I have compiled OpenJDK several times on HC1. Takes 1 hour when running on SSD, which should not be much slower for you with USB 3.0/SSD.

Currently running the OpenJDK 11.0.1 right from the Armbian distro. Could post either one at postman.

Cheat sheet for building yourself:

hg clone -u jdk-11.0.2-ga ​http://hg.openjdk.java.net/jdk-updates/jdk11u;cd jdk11u
bash configure --disable-warnings-as-errors <--with-jtreg=/path/to/jtreg>
make JOBS=4 images
make test will probably fail, takes a full day

[sam]

Java version 10.0.2 (installed with the package openjdk-11-jre) also doesnt work without errors.

Can you pls upload your 11.0.1 build on postman?

[jogger]

Its out

[sam]

Replying to jogger:

Its out

Thanks a lot. Just began to download it and can continue downloading in about 24hours.

I will post some updates after the "installation".

[sam]

Found some time and compiled jdk-11.0.2 myself. Works since 2 days without any problems.
I hope it stays that way.
Thanks jogger
