Steve So I tried out the patch (took some time to build ppa:james-page/junk) and did some more digging when it did not appear to work.
I managed to capture a stacktrace when the issue occured: java.lang.UnsatisfiedLinkError: Unable to load library 'pam': libpam.so: cannot open shared object file: No such file or directory at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:164) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:237) at com.sun.jna.Library$Handler.(Library.java:140) at com.sun.jna.Native.loadLibrary(Native.java:374) at com.sun.jna.Native.loadLibrary(Native.java:359) at org.jvnet.libpam.impl.PAMLibrary.(PAMLibrary.java:132) at sun.misc.Unsafe.ensureClassInitialized(Native Method) at sun.reflect.UnsafeFieldAccessorFactory.newFieldAccessor(UnsafeFieldAccessorFactory.java:43) at sun.reflect.ReflectionFactory.newFieldAccessor(ReflectionFactory.java:140) at java.lang.reflect.Field.acquireFieldAccessor(Field.java:936) at java.lang.reflect.Field.getFieldAccessor(Field.java:917) at java.lang.reflect.Field.get(Field.java:376) at com.sun.jna.Native.loadLibraryInstance(Native.java:398) at com.sun.jna.Native.getStructureAlignment(Native.java:507) at com.sun.jna.Structure.setAlignType(Structure.java:191) at com.sun.jna.Structure.(Structure.java:149) at com.sun.jna.Structure.(Structure.java:145) at com.sun.jna.Structure.(Structure.java:141) at com.sun.jna.Structure.(Structure.java:132) So it looks like the issue (or maybe one of them) is actually in libjna- java; I'm pretty sure that openjdk may exhibit the same symptoms but the issue reading libpam.so is generated outside of openjdk. I'll look into the specific library to see what its doing - suspect it something horrible with guessed paths but it may be related to the java.library.path variable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/737603 Title: JNI unable to find libpam.so -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
