Unstable hash due to unstable class names.

[DaanVanYperen]

Javassist class naming isn't stable between builds which causes the exception hash to shift.

com.example.Service_$$_javassist_seam_92/throwException
com.example.Service_$$_javassist_seam_43/throwException

Since others might be stuck with the same legacy frameworks decided to submit this workaround. It kills $$ suffixes. No guarantees how nice it plays with other bytecode manipulation libs.

Thanks for making exhash. :)

    private class StacktraceJavassistWorkaround implements IStacktrace {
        private final String cleanTrace;
        private static final String REGEXP_MATCH_JAVASSIST_SUFFIX = "_\\$\\$_\\S+(?=\\/)"; // cut off dynamic _$$_ bit

        public StacktraceJavassistWorkaround(IStacktrace stacktrace) {
            cleanTrace = filterJavassistSuffix(stacktrace.getStacktraceText());
        }

        private String filterJavassistSuffix(String stacktraceText) {
            final StringBuilder builder = new StringBuilder();
            new BufferedReader(new StringReader(stacktraceText))
                    .lines().forEach(s -> {
                builder.append(s.replaceAll(REGEXP_MATCH_JAVASSIST_SUFFIX, "")).append("\n");
            });
            return builder.toString();
        }

        @Override
        public String getStacktraceText() {
            return cleanTrace;
        }
    }
