Bug 915126 – net-wireless/unifi-7.5.176 does not start on Java 17: Unable to make private java.time.Instant(long,int) accessible

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Jyrki Launonen 2023-10-03 17:51:04 UTC]

7.5.176 updated required Java version, which is marked in RDEPEND with virtual/jre:17, but even so openjdk-bin:17 won't allow Unifi to start due a long nested exception with final exception:

  Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make private java.time.Instant(long,int) accessible: module java.base do
es not "opens java.time" to unnamed module @43c3d622

Linked in URL is a comment from vendor explaining to someone else what arguments are needed, among which are a bunch of --add-opens -arguments. Adding them in the ebuild for java-pkg_dolauncher --java_args string resolves the issue.
Something like this:

	java-pkg_dolauncher \
		unifi \
		--java_args '-Dorg.xerial.snappy.tempdir=/usr/lib/unifi/tmp -Djava.library.path= --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.time=ALL-UNNAMED --add-opens java.base/sun.security.util=ALL-UNNAMED --add-opens java.base/java.io=ALL-UNNAMED --add-opens java.rmi/sun.rmi.transport=ALL-UNNAMED' \
		--jar ace.jar \
		--pwd '/usr/lib/unifi'

Whether the other parameters described in URL are needed I do not know nor have tried; this seems to be the smallest change required.


Reproducible: Always

Steps to Reproduce:
1. emerge =net-wireless/unifi-7.5.176  (after keywords)
2. rc-service unifi start  (or similar)
3. see /var/log/unifi/server.log for errors

Actual Results:  
Opening the service web page gives 404 not found.

Expected Results:  
Opening the service web page gives Unifi login page.

I confirm!
Same issue with:
* dev-java/openjdk-17.0.6_p10
* net-wireless/unifi-7.5.176

I haven't tried the fix, but it makes sense indeed.

Successfully started unifi 7.5.176 with =dev-java/openjdk-jre-bin-17.0.6_p10 after adding:
--add-opens java.base/java.time=ALL-UNNAMED
to gjl_java_args in /usr/bin/unifi

Patch for unifi-7.5.176.ebuild

Works great! This can be fixed in the build itself (patch attached).

However please note that --add-opens is not supported yet in JDK 8, as far as I know.

Java 17 is a requirement for Unifi 7.5.176 AFAIK.
