Created attachment 191753 [details] Simplified report demonstrating the problem Hello, We use the BIRT 2.5.2 runtime in a J2EE web application (running in OC4J on Windows) to generate and serve reports. One of our reports is failing when several users try to generate it in parallel. Depending on the situation, it fails with NullPointerException or StringIndexOutOfBoundsException (see stacktraces below) but always in some part of the code which is related to text areas. Our report is quite long and uses a custom data source so I created a simplified report that reproduces the problem (see attachment). The simplified report can be executed in a JUnit test for example and it contains multiline text elements with content types html and plain. The plain text data contains CRLFs (\r\n) and the html data contains <BR> tags. For the problem to occur, you must run multiple occurences of the report in parallel. I tried upgrading to BIRT 2.6.2 but it fails in a similar way.
