and I get this error when I run languagetool (the GUI doesn’t start, it’s not just a warning):

Does adding -Djdk.xml.totalEntitySizeLimit=125000 on the command line help as a workaround? Otherwise, I think JDK24 isn’t supported yet by LT, and you’ll need to use e.g. JDK 17.

Adding -Djdk.. unfortunately doesn’t work (tried it also by adding it to /usr/bin/languagetool (see below for workaround)).

Previous version was 23 (gitlab.archlinux . org/archlinux/packaging/packages/java-openjdk/-/commits/main) btw.

My workaround:

  • sudo pacman -S jre21-openjdk (v21 is the latest non-24 version with long term support, I guess) (installing a concurrent different version is possible and supported on Arch (see))
  • I don’t use archlinux-java, as this would change the java version globally
  • Instead I edited /usr/bin/languagetool and changed the very last line 71 from
    "$JAVA_HOME/bin/java" -cp $CP -Dsun.java2d.uiScale=4 $GUI_command "${argv[@]}"
    to
    "$JAVA_HOME/usr/lib/jvm/java-21-openjdk/bin/java" -cp $CP -Dsun.java2d.uiScale=4 $GUI_command "${argv[@]}"
  • Running languagetool works again
  • The -Dsun.java2d.uiScale=4 is also added by me to fix the GUI being tiny on my 4K screen

I can get all DE unit tests pass except one by adding these two properties:
-Djdk.xml.totalEntitySizeLimit=0 -Djdk.xml.entityExpansionLimit=0
It seems that they changed the limit in jdk24 from 5 million to 100k:

I’ve pushed a commit to mitigate that problem in a jdk24 branch
I’ve set the xml limits at more global level and also updated guava to remove a warning.
Unfortunately there’s another warning coming from jna and even updating it to the latest version didn’t make all warnings go away so I didn’t push it.
Note: there are still other 2 places trying to set xml limits for the SAX parser and we may want to consolidate it.
Note: with jdk24 I have one test in [de] failing and also we have some French tests failing starting with jdk21 (I think there were some regressions since we pushed support for jdk21) so I could not verify it all the way.
It would be nice to make LT 6.6 jdk24-compatible.
