Function rubyStyleEscape

src/java/frameworks/java_opts.go:185–196

rubyStyleEscape escapes a Java option exactly like the Ruby buildpack Ruby source: lib/java_buildpack/framework/java_opts.rb:40-41 .map { |java_opt| /(? .+?)=(? .+)/ =~ java_opt ? "#{key}=#{escape_value(value)}" : java_opt } Strategy: Split on first '=' and escape only the VALUE part

(javaOpt string)

//	"-Dkey=value with spaces"           → "-Dkey=value\\ with\\ spaces"
//	"-XX:OnOutOfMemoryError=kill -9 %p" → "-XX:OnOutOfMemoryError=kill\\ -9\\ \\%p"
func rubyStyleEscape(javaOpt string) string {
	idx := strings.IndexByte(javaOpt, '=')

	if idx == -1 || idx == len(javaOpt)-1 {
		return javaOpt // No '=' or ends with '='
	}

	key := javaOpt[:idx]
	value := javaOpt[idx+1:]

	return key + "=" + escapeValue(value)
}

// escapeValue escapes a string for shell safety using Ruby's escape_value method
//
