I think upgrading to fedora32 has broken javaws.
$ javaws some.jnlp selected jre: /usr/lib/jvm/jre-1.8.0-openjdk thread 'main' panicked at 'Error spawning JVM process, java executable: [/usr/lib/jvm/jre-1.8.0-openjdk], arguments: [["-splash://usr/share/icedtea-web/javaws_splash.png", "-Xbootclasspath/a://usr/share/icedtea-web/javaws.jar:/usr/share/java/rhino.jar:/usr/share/java/tagsoup.jar:/usr/share/java/IPAddress/ipaddress.jar:/usr/lib/jvm/jre-1.8.0-openjdk/lib/ext/nashorn.jar:", "-classpath", "/usr/lib/jvm/jre-1.8.0-openjdk/lib/rt.jar:/usr/lib/jvm/jre-1.8.0-openjdk/lib/ext/jfxrt.jar:", "-Dicedtea-web.bin.name=javaws", "-Dicedtea-web.bin.location=/usr/libexec/icedtea-web/javaws", "net.sourceforge.jnlp.runtime.Boot", "some.jnlp"]]', src/os_access.rs:42:19 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
i think i may have made things worse by trying
dnf reinstall java-1.8.0-openjdk.x86_64 java-1.8.0-openjdk-headless.x86_64 icedtea-web
i have suspected that openjdk was maybe a bit messed up for a while but it was working ok. i’d be grateful for a it of expertise understanding how i resolve this mess
