BTW, running gkeytool without any args shows the problem too. When libjava is
built with -g -O2, I get
Exception in thread "main" java.lang.NoClassDefFoundError:
gnu.classpath.tools.keytool.Main
at java.lang.Class.initializeClass(natClass.cc)
Caused by: java.lang.IllegalMonitorStateException: current thread not owner
at java.lang.Object.notifyAll(natObject.cc:1437)
at gnu.gcj.runtime.SystemClassLoader.findClass(natSystemClassLoader.cc:29)
at java.lang.ClassLoader.loadClass(ClassLoader.java)
at java.lang.ClassLoader.loadClass(ClassLoader.java:387)
at java.lang.Class.initializeClass(natClass.cc:728)
But note that natObject.cc:1437 is a lie! The real failure occurs
natObject.cc:1431 and it looks like the two identical throws have merged.
Putting a break on the right place, I see
(gdb) p this
$8 = (java::lang::Object * const) 0xffc6aec
<gnu::classpath::tools::keytool::Main$ShutdownHook::class$>
(gdb) p/x addr
$9 = 0xffc6aec
Uh oh! The address is not 8-byte aligned, so one of the flag bits appears to
be set. This is why we appear to have locking problems.
