SequenceInputStream boosted: Latest OpenJDK Contrib | Java Coding | Head Crashing Informatics 68
If you are using SequenceInputStream, you will notice that it pulls all data into the JVM’s memory, just to drain it to another I/O sink. This is inefficient and slow. With my latest contribution contained in #OpenJDK 20, this will … Continue reading

Small Change with BIG EFFECT | OpenJDK Contrib | Java Coding | Head Crashing Informatics 67
Contributions to #OpenJDK don’t have to be huge always. Sometimes it is the small things that have BIG EFFECT. For example if a class was intended to be non-synchronized (hence: fast), implicitly is synchronized by mistake (hence: slow), is finally … Continue reading

I boosted the PushbackInputStream | OpenJDK Contrib | Java Coding | Head Crashing Informatics 66
As #PushbackInputStream is quite similar to #BufferedInputStream, it was rather easy for me to apply the performance optimizations I already developed for BufferedInputStream to the PushbackInputStream. The contribution was accepted in November 2022, so it is now part of #OpenJDK … Continue reading

BufferedInputStream boosted AGAIN by OpenJDK Contrib | Java Coding | Head Crashing Informatics 65
Recently I boosted #BufferedInputStream by contributing to #OpenJDK. There was one case open, in which performance did not excel. Now in my new contribution to OpenJDK, which is contained in #Java 20, I fixed this – so in two thirds … Continue reading

Good bye, application/svg+xml | The Two Minutes Tuesday 035 | Jakarta REST 4.0
Jakarta REST 4.0 will be backwards-incompatible, and here comes one of the first notable changes: The (actually wrong) MIME type application/svg+xml will not be provided out of the box anymore (at least eventually). If you want to use it (or … Continue reading

BufferedInputStream boosted: Another OpenJDK Contrib | Java Coding | Head Crashing Informatics 63
Last year I contributed a performance optimization to #OpenJDK that makes I/O operations much faster. Strange but true, with existing code often it did not chime in. The reason is that BufferedInputStream was used in many existing applications, which unfortunately … Continue reading
