Nick Gasson 953e92402a perf jvmti: Fix jitdump for methods without debug info ... If a Java class is compiled with -g:none to omit debug information, the JVMTI plugin won't write jitdump entries for any method in this class and prints a lot of errors like: java: GetSourceFileName failed with JVMTI_ERROR_ABSENT_INFORMATION The call to GetSourceFileName is used to derive the file name `fn`, but this value is not actually used since commit ca58d7e64b ("perf jvmti: Generate correct debug information for inlined code") which moved the file name lookup into fill_source_filenames(). So the call to GetSourceFileName and related code can be safely removed.
