IV82165: FILE PATHS AND SYSTEM PROPERTIES CONTAINING UNICODE ESCAPE SEQUE NCES CORRUPTED

APAR status

• Closed as program error.

Error description

• Error Message: java -classpath C:\Users\u1234\libs HelloWorld
  Error: Could not find or load main class HelloWorld
  or
  java -Dfoo=\u0058 ...
  system property "foo" is set to "X" (Unicode code point 0x58) in
  the application.
  .
  Stack Trace: N/A
  .
  Problem occurs only on Windows.  Class paths are corrupted if
  the directory or file name starts with 'udddd' (where "d" is a
  decimal digit), or a system property contains "\udddd".
  

Local fix

Problem summary

• The Java VM misinterprets system properties set via the launcher
  or JNI Invocation API,
  including search paths, containing "\udddd" on Windows
  as a Unicode escape sequence.
  System properties set from Java code are not affected.
  

Problem conclusion

• The Java VM command line processing code has been changed to
  translate Unicode escape sequences only if the
  "-Xargencoding" option (without encoding specifiers) is used.
  This matches the behaviour of the Java VM prior to Java 7.1.
  .
  This APAR will be fixed in the following Java Releases:
     7 R1 SR3 FP40  (7.1.3.40)
     8    SR3       (8.0.3.0)
  .
