bash-3.00$ cat check_HistoricalNames_12b2/report/summary.txt sun/nio/cs/CheckHistoricalNames.java  Failed. Execution failed: `main' threw exception: java.lang.Exception: Failed canonical names : mismatch for UnicodeBig - expected UnicodeBig, got UTF-16
bash-3.00$ cat check_HistoricalNames_11b6/report/summary.txt
sun/nio/cs/CheckHistoricalNames.java  Passed. Execution successful
Comments
SUGGESTED FIX Fix would be to remove UnicodeBig alias added to Charset UTF_16 in StandardCharset.java. ------- StandardCharsets.java ------- 61,62d60 < "unicode", < "UnicodeBig"
16-03-2006
EVALUATION I can confirm that this is a side effect of fix to bug 6292322. This has happened because of a change wherein UnicodeBig has been added as alias to canonical name UTF-16 in StandardCharsets.java.
