  • Good Java Source Code

    is this the source code?
  • Schrödinger's Java function
    1 project | | 7 Jan 2022
    Yeah weird, you can see the class for it at the OpenJDK GitHub. Taking a glance at it seems it's something to do with threading and ensuring all the VM shutdown steps are complete before actually terminating the VM?
  • Ask HN: Is this weird folder name indication of attempted log4shell attack?
    2 projects | | 27 Dec 2021

    If the requested directory name has certain "inappropriate" characters in it, it'll encode it using Base64.byteArrayToAltBase64, which is a non-standard base64 encoding using the alphabet defined here:

  • Java documentation explanation

    Package has to match the folder structure and there needs to be a "package x.y.z" declaration in the beginning of the file. See this
  • intro to rust... is more intelligent than most languages? (discussion?)

    Most, if not all, languages are open-source. Here are Java, Kotlin and Ruby, for example.
  • What is the complexity of contains method of HashSet?
    1 project | | 7 Dec 2021
    Not terribly relevant but it is worth noting that HashSet is implemented using an HashMap:

    I think you're making my point for me, no? Your arguments are all variants on "I don't understand modern Java and prefer to keep writing buffer overflows than finding out".

    To answer your questions:

    1. Java is these days like UNIX, there are lots of compatible "distros". OpenJDK is the upstream on which most of them are based. You can just use that unless you have some particular preference for the other vendors.

    2. You don't need to install Java alongside your app. The JVMs is just a library and a few data files. You can easily bundle it with your app and the user will never know.

    3. JCA/JSSE is built in to Java so there's nothing to build. Additionally you don't have to build Java libraries to use them anyway, because binary distribution works so everyone just distributes binary JAR files.

    4. The source code is spread around several modules because JCA is pluggable. But for example a lot of the crypto code is found here:

    5. Oracle maintains it. It's released under the GPL with Classpath exception license. They aren't going to come after you for using it - there are 12 million Java developers in the world. The only company that has ever got sued is Google and that's because they violated the (at the time non open source) license of Java to make a mobile version that wasn't from Sun. Since then Java became fully open source and this no longer applies, and it'd have never applied to normal users of it anyway.

    I'm not trying to convince you here of anything, only to point out that everyone saying "there was no alternative" is just wrong. The failure mode here is not sufficiently advanced fuzzers. The failure is that there has been an alternative to NSS for years but C++ shops like Mozilla keep maintaining crappy decades old C libraries with memcpy calls all over the place, because they know and like C. That's it. That's all it boils down to.
