[ https://issues.jboss.org/browse/AS7-5106?page=com.atlassian.jira.plugin.s... ] Ste Gr updated AS7-5106: ------------------------ Description: As soon as the http response should be send, there might be the problem, where the headers exceed the size of the internal output buffer. (see https://issues.jboss.org/browse/ARQ-982) * No boundary check on the array 'buf' of InternalOutputBuffer * problem: The whole sendHeader-routine is not able to split the send of http headers. Example stack trace (arquillian warp is adds the big header): {noformat} ArrayIndexOutOfBoundsException InternalOutputBuffer.write(String) line: 698 InternalOutputBuffer.write(MessageBytes) line: 607 InternalOutputBuffer.sendHeader(MessageBytes, MessageBytes) line: 479 Http11Processor.prepareResponse() line: 1648 Http11Processor.action(ActionCode, Object) line: 998 Response.action(ActionCode, Object) line: 188 InternalOutputBuffer.doWrite(ByteChunk, Response) line: 552 Response.doWrite(ByteChunk) line: 594 OutputBuffer.realWriteBytes(byte[], int, int) line: 398 ByteChunk.flushBuffer() line: 449 ByteChunk.append(byte[], int, int) line: 349 OutputBuffer.writeBytes(byte[], int, int) line: 426 OutputBuffer.write(byte[], int, int) line: 415 CoyoteOutputStream.write(byte[], int, int) line: 89 CoyoteOutputStream.write(byte[]) line: 83 NonWritingPrintWriter.finallyWriteAndClose(ServletOutputStream) line: 58 WarpFilter.doFilter(ServletRequest, ServletResponse, FilterChain) line: 189 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 280 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 248 TransactionWebFilter.doFilter(ServletRequest, ServletResponse, FilterChain) line: 38 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 280 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 248 NTLMFakeFilter.doFilter(ServletRequest, ServletResponse, FilterChain) line: 33 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 280 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 248 StandardWrapperValve.invoke(Request, Response) line: 275 StandardContextValve.invoke(Request, Response) line: 161 WebNonTxEmCloserValve.invoke(Request, Response) line: 50 SecurityContextAssociationValve.invoke(Request, Response) line: 153 StandardHostValve.invoke(Request, Response) line: 155 ErrorReportValve.invoke(Request, Response) line: 102 StandardEngineValve.invoke(Request, Response) line: 109 CoyoteAdapter.service(Request, Response) line: 368 Http11Processor.process(Socket) line: 877 Http11Protocol$Http11ConnectionHandler.process(Socket) line: 671 JIoEndpoint$Worker.run() line: 930 Thread.run() line: not available {noformat} was: As soon as the http response should be send, there might be the problem, where the headers exceed the size of the internal output buffer.
