When trying to compile a jsp that uses JSTL, I have a NPE in the JSP compiler. I am attaching a zip that contains a self contained sample showing the bug with correct dependencies via Maven: Have Maven installed. Unzip the bug.zip attached file (there is a JSP and a simple Main calling the JSPC compiler with the correct flags) cd bug/jspcBug mvn install mvn exec:java -Dexec.mainClass="bug.JSPCBug" See the NPE: ava.lang.NullPointerException at org.apache.jasper.servlet.JspCServletContext.getResource(JspCServletContext.java:344) at org.apache.jasper.JspCompilationContext.getResource(JspCompilationContext.java:283) at org.apache.jasper.JspCompilationContext.getLastModified(JspCompilationContext.java:359) at org.apache.jasper.compiler.TagLibraryInfoImpl.<init>(TagLibraryInfoImpl.java:138) at org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:411) at org.apache.jasper.compiler.Parser.parseDirective(Parser.java:469) at org.apache.jasper.compiler.Parser.parseElements(Parser.java:1455) at org.apache.jasper.compiler.Parser.parse(Parser.java:139) at org.apache.jasper.compiler.ParserController.doParse(ParserController.java:229) at org.apache.jasper.compiler.ParserController.parse(ParserController.java:100) at org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:200) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:375) at org.apache.jasper.JspC.processFile(JspC.java:1205) at org.apache.jasper.JspC.execute(JspC.java:1356) at org.apache.jasper.JspC.main(JspC.java:270) at bug.JSPCBug.main(JSPCBug.java:23) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.codehaus.mojo.exec.ExecJavaMojo$1.run(ExecJavaMojo.java:297) at java.lang.Thread.run(Thread.java:724) org.apache.jasper.JasperException: java.lang.NullPointerException
Created attachment 31345 [details] bug sample Simple Maven project exposing the NPE. It has 1 Main that calls the jsp compiler with correct parameters and the jsp. The pom.xml has all the correct and latest dependencies.
Thanks for the report. This has been fixed in 8.0.x and will be included in 8.0.4 onwards.
