FULL PRODUCT VERSION :
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]
Service Pack 3

A DESCRIPTION OF THE PROBLEM :
If ZipInputStream is used to read a zip file containing one
or more files with Chinese, Japanese or Korean names, the
getNextEntry method throws an IllegalArgumentException.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a zip file containing at least one file with a
Chinese, Japanese or Korean filename.
2. Try to read using a ZipInputStream.

EXPECTED VERSUS ACTUAL BEHAVIOR :
Should return a valid entry with the correct filename
instead of throwing an exception.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
java.lang.IllegalArgumentException

    at java.util.zip.ZipInputStream.getUTF8String(ZipInputStream.java:291)

    at java.util.zip.ZipInputStream.readLOC(ZipInputStream.java:230)

    at java.util.zip.ZipInputStream.getNextEntry(ZipInputStream.java:75)

REPRODUCIBILITY :
This bug can be reproduced always.

Same problem reported by a CAP member from Germany:

J2SE Version (please include all output from java -version flag):
  java version "1.4.1"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
  Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)

and

  java version "1.5.0-beta"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b16)
  Java HotSpot(TM) Client VM (build 1.5.0-beta-b16, mixed mode)


Does this problem occur on J2SE 1.3, 1.4 or 1.4.1? Yes / No (pick one)
  Yes

Operating System Configuration Information (be specific):
  English Linux and German Win2K

Bug Description:
  A ZIP file with entries that contain german umlauts. When read
  read these entries using ZipInputStream.getNextEntry() it throws an
  IllegalArgumentException at:

Exception in thread "main" java.lang.IllegalArgumentException
         at
java.util.zip.ZipInputStream.getUTF8String(ZipInputStream.java:298)
         at java.util.zip.ZipInputStream.readLOC(ZipInputStream.java:237)
         at
java.util.zip.ZipInputStream.getNextEntry(ZipInputStream.java:73)
         at ZipUmlauts.main(ZipUmlauts.java:22)

  It would be better, if the getUTF8String() method would just ignore
  these "illegal" characters or add them "as-is".

Test Program: (ZipUmlauts.java umlauts.zip)
