JDK-8217038 | 11 | Raymond Gallardo | P3 | Resolved | Fixed |
Background:
After one customer upgraded from 5u17, garbled text occurred on their application where "UNICODE" was used.
Then they found it was caused by the fix ofJDK-6292322.
The behavior of String#getBytes("UNICODE") was changed by the fix.
before: return UTF-16 of Litle Endian with BOM
after : return UTF-16 of Big Endian with BOM
This is an enhancement request that requires Sustaining resolution.
Exception is not raised when an invalid name "UNICODE" is used in
java.lang.String#getBytes. However, "UNICODE" is not supported
according to the page below:
http://docs.oracle.com/javase/1.5.0/docs/guide/intl/encoding.doc.html
The test case Test.java
class Test{
public static void main(String[] args) throws
java.io.UnsupportedEncodingException{
System.out.println("Hello".getBytes("UNICODE"));
}
}
To reproduce:
1. jdk8u25/bin/javac Test.java
2. jdk8u25/bin/java Test
Suggested Fix:
Does strict check on API unsupported parameters
Make noticeable announcement if incompatibility change is made
