  After renaming jre to jre15, java -fullversion gives a  wrong
  Java level and java -version command fails to execute.
  

Local fix

Problem summary

• After applying APAR PM13858, when application change the jre
  directory to jre15, JDK consider it as the sdk/bin directory and
  set the JRE directory by appending jre/bin. As jre15 is
  originally the JRE directory, JVM could not find the directory
  when a jre is appended to the original JRE directory (jre15),
  JVM could not find the dll expected in jre directory.
  

Problem conclusion

• This defect will be fixed in:
  1.4.2 SR13 FP9 (AIX)
  5.0.0 SR12 FP4
  1.4.2 SR13 FP9 (Linux)
  .
  JVM is updated to handle modified JRE directory name.
  .
  To obtain the fix:
  Install build 20110226 or later
