http://issues.apache.org/bugzilla/show_bug.cgi?id=39772 Summary: RE internal error: Invalid opcode '0' Product: Regexp Version: unspecified Platform: Sun OS/Version: Solaris Status: NEW Severity: blocker Priority: P1 Component: Other AssignedTo: regexp-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I have a Web application using struts, the page parses a date string, intermittently, I am getting following error: java.lang.Error: RE internal error: Invalid opcode '0' at org.apache.regexp.RE.internalError(Unknown Source) at org.apache.regexp.RE.matchNodes(Unknown Source) at org.apache.regexp.RE.matchNodes(Unknown Source) at org.apache.regexp.RE.matchAt(Unknown Source) at org.apache.regexp.RE.match(Unknown Source) at org.apache.regexp.RE.match(Unknown Source) at org.apache.regexp.RE.match(Unknown Source) at com.ew.util.Regex.getDatePattern(Regex.java:95) at com.ew.util.DateUtil.parse(DateUtil.java:69) at com.parser.ReportParser.parseReport(ReportParser.java:40) the getDatePattern code looks like: public static String getDatePattern(String dateStr) throws EWException { RE regexp = new RE(); String datePattern = null; try { // if no data string, throw exception if (StringUtils.isEmpty(dateStr)) { throw new EWException(new IllegalArgumentException( "The date string is empty")); } else { // if one Date REProgram is null, consider all of them are // yet instatiated. if (dateFormatMap.size() == 0) { dateFormatMap.put(DATE_PATTERN_0, compiler.compile(DATE_0)); dateFormatMap.put(DATE_PATTERN_1, compiler.compile(DATE_1)); dateFormatMap.put(DATE_PATTERN_2, compiler.compile(DATE_2)); dateFormatMap.put(DATE_PATTERN_3, compiler.compile(DATE_3)); dateFormatMap.put(DATE_PATTERN_4, compiler.compile(DATE_4)); dateFormatMap.put(DATE_PATTERN_5, compiler.compile(DATE_5)); dateFormatMap.put(DATE_PATTERN_6, compiler.compile(DATE_6)); dateFormatMap.put(DATE_PATTERN_7, compiler.compile(DATE_7)); dateFormatMap.put(DATE_PATTERN_8, compiler.compile(DATE_8)); dateFormatMap.put(DATE_PATTERN_9, compiler.compile(DATE_9)); } // find the pattern that matches the date string Iterator keys = dateFormatMap.keySet().iterator(); String pattern; while(keys.hasNext()) { pattern = (String) keys.next(); regexp.setProgram((REProgram)dateFormatMap.get(pattern)); if (regexp.match(dateStr)){ datePattern = pattern; break; } } .................. Once the problem happens, we have to restart the server. Sometimes, we have to restart the server couple of times to remove the error. But the problem is not that easy to reproduce. it happens intermittently in production. We could not reproduce it in QA. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
