Check if Java bytecode contains debug symbols

Question

Hello,

I would like to know how can I check if a compiled Java class contains debug symbols. The problem is that I compile an application from ant with debug="on", but a specific JVM throws an exception: it says that the debug symbols are missing.

Thanks.

If you run javap -v on the class file, you will see the debug information that is available. It is worth compiling a simple test class with different -g option settings and looking at the results with javap.
