  When the LIBPATH value is set to shared libraries of other JVM ,
  then even java -version dumps core on AIX PPC32 systems
  

Local fix

• The problem can be work around by:
      1) Setting the LIBPATH to the current JVM shared libraries.
       OR
      2) Remove the LIBPATH to other JVM shared libraries.
       OR
      3) Unsettiing the env varaiable LDR_CNTRL.
  

Problem summary

• When JVM identified the LIBPATH to other JVM shared libraries,
  it consider them as its own shared libraries and did not include
  the path to its actual shared libraries.
  

Problem conclusion

• The java launcher has been updated to make sure that the
  environment for the java process is set correctly before
  launching the JVM.
  .
  This defect will be fixed in:
  6.0.0 SR11
  6.0.1 SR3
  

Temporary fix
