IllegalArgumentException on jbosss 5.1.0 while reading http

[daphna deutsch]

Hi,
I'm trying to migrate from jboss 4.2.3 to jboss 5.1.0 (JDK 6.0).
My application reads xml over http requests from several clients.

After migrating to jboss 5 and sending the xml request I'm sometime getting IllegalArgumentException from tomcat. Same request may sometime works fine and sometime gets the exception.

 
java.lang.IllegalArgumentException
at java.nio.Buffer.position(Buffer.java:218)
at org.apache.tomcat.util.buf.B2CConverter.convert(B2CConverter.java:84)
at org.apache.catalina.connector.InputBuffer.realReadChars(InputBuffer.java:403)
at org.apache.tomcat.util.buf.CharChunk.substract(CharChunk.java:416)
at org.apache.catalina.connector.InputBuffer.read(InputBuffer.java:432)
at org.apache.catalina.connector.CoyoteReader.read(CoyoteReader.java:105)
at org.apache.catalina.connector.CoyoteReader.readLine(CoyoteReader.java:158)

Here is a sample of my code that read the request. Same code work fine on jboss 4.0.5 and 4.2.3.

   
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
{
 BufferedReader reader = request.getReader();
 String line;
 while ((line = reader.readLine()) != null){
 result.append(line);
 }
}

 

how can i solve this?

Thanks,
Daphna

I opened a defect for JBoss: https://jira.jboss.org/jira/browse/JBAS-7817
It was accepted.

Are you able to resolve this issue?Any workaround you have applied for Jboss 5.1.0 ?
Seems they have resolved it in 6.0.0.M3.

I was using BufferedReader readLine() API , using read() I was able to solve this issue. read() will be slower than readLine() , because of blocking calls.

  
StringBuilder s = new StringBuilder();
			int c = 0;
			//reading char by char as there is an issue in JBOSS 5.1.0 GA
			while((c = requestReader.read()) != -1){
				s.append((char)c);
			}

Hi,

Because what we used is JBoss Community edition, there is no support for this open source edition. If you used a JBoss commercial edition, you can request a fix for it.

As i know there is no workaround for it unless you want to fix it by yourself.
