Public bug reported:
When I load NetBeans (whether via the GUI or from a command line), the
splash screen appears and loads as far as "Turning on modules..."
(usually; very occasionally it gets stuck at "Reading module storage..."
instead). The splash screen then freezes for approximately 11-12 seconds
and then the entire program exits. Expected behaviour is that when I
load NetBeans, the loading process finishes and then the application's
main interface opens, without the process exiting.
I have two JREs installed, /usr/lib/jvm/java-8-openjdk-
amd64/jre/bin/java and /usr/lib/jvm/java-11-openjdk-amd64/bin/java. The
same behaviour of the splash screen occurs regardless of which JRE is
pointed at via "/usr/bin/java".
I also have two versions of javac installed, /usr/lib/jvm/java-8
-openjdk-amd64/bin/javac and /usr/lib/jvm/java-11-openjdk-
amd64/bin/javac. The choice of javac that "/usr/bin/javac" points to
does influence the results. I suspect that the difference is immaterial
but am mentioning it just in case:
* When using the Java 8 version of javac, no message is printed when NetBeans
exits this way; it simply exits to the command prompt (or the desktop if loaded
via the GUI) without printing anything. The exit status is 2.
* When using the "java-11-openjdk-amd64" version of javac (which claims to be
"javac 10.0.1" in its version info; thus I'm not clear on whether this is Java
10 or Java 11), the following messages are printed on standard output/error,
before it exits with exit status 2 (I suspect these are unrelated to the crash,
but including them just in case):
{{{
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.netbeans.ProxyURLStreamHandlerFactory
(file:/usr/share/netbeans/platform18/lib/boot.jar) to field java.net.URL.handler
WARNING: Please consider reporting this to the maintainers of
org.netbeans.ProxyURLStreamHandlerFactory
WARNING: Use --illegal-access=warn to enable warnings of further illegal
reflective access operations
WARNING: All illegal access operations will be denied in a future release
}}}
In an attempt to get more information about where the crash is
occurring, I ran NetBeans with -J-verbose (thus causing the JVM to
output which classes are loaded, perhaps indicating how far it got with
initialisation before the crash); the resulting file is attached as
netbeans-J-verbose.txt. Under this configuration, it consistently
crashes almost immediately after loading sun.awt.X11.XSystemTrayPeer.
(I've been testing with the Java 8 versions of java and javac.) This
might or might not be a useful lead.
Are there any tests that might give more useful information than the
limited information I have here?
This behaviour started immediately after an upgrade from Artful to
Bionic. I'm running Cinnamon as my desktop.
