Compilation error: JSR / RET are not supported using the computeFrames parameter

Question

Getting this error in an IntelliJ project when compiling java files. No specific source file specified, but it does not work with this error.

Removing the following compiler flags resolves the error:

-source 1.5 -target 1.5 

However, they should be there, since we focus on Java 5. Is there any specific code (possibly a try/catch ) that causes this error?

Answer 1

JSR / RET commands are displayed in byte code when try / finally fragments appear in the source. Javac 1.6+ doesn't seem to highlight them even with -target 1.5, but the Eclipse java compiler does.

Example

 public class JSRDemo { public static void main(String[] args) { try { bodyOfTry(); } finally { bodyOfFinally(); } } ... 

Bytecodes
