IV52646: UNSATISIFIED LINK ERROR IF LD_LIBRARY_PATH CONTAINS CONFLICTING LIBRARY WITH JAVA LIBRARIES ON LINUX

APAR status

• Closed as program error.

Error description

• Error Message: java.lang.UnsatisfiedLinkError: nio:-
  (/tmp/install.dir.31437/Linux/resource/jre/lib/i386/libnio.so:
  symbol
  NET_Bind, version SUNWprivate_1.1 not defined in file libnet.so
  with
  link time reference)
  .
  Stack Trace:
  java.lang.ClassLoader.loadLibraryWithPath(ClassLoader.java:1213)
  at
  java.lang.ClassLoader.loadLibraryWithClassLoader(ClassLoader.jav
  a:1177)
  at java.lang.System.loadLibrary(System.java:530)
  .
  

Local fix

• - Move the conflicting library to a different path which is not
  in the LD_LIBRARY_PATH.
  OR
  - Remove the path which contains conflicting library from the
  LD_LIBRARY_PATH.
  

Problem summary

• The compiler (gcc) version used for generating JDK 7 libraries
  used the option runpath by default. Runpath gives precedence to
  LD_LIBRARY_PATH rather than the JDK relative path which Java
  uses to search for its libraries. Hence, any library name which
  is conflicting with JDK library exists in LD_LIBRARY_PATH can
  result in the Unsatisified link error.
  

Problem conclusion

• This APAR will be fixed in the following Java Releases:
     7    SR7       (7.0.7.0)
     7 R1 SR1       (7.1.1.0)
  .
  The JDK libraries have been generated by disabling the runpath
  option.
  

Temporary fix
