Due to the compiler not being thread safe, the compiled source code for JSPs did not comply with the JVM specification for class file structure. This is only an issue for browser based compilations. The JSPBatchCompiler is not affected by this threading issue.Problem conclusion To resolve the threading issue with the JDK, WebSphere will synchronize the loading and compilation of JSPs when this JVM system is enabled.Temporary fix Comments
