Title

Java 25 Networking (PPSA99868)

Content version tested

01.000.003, release Network_Probe-v01.000.003 of mateo-cogeanu/ps5-java25-homebrew (PPSA99868-network-pass-01.000.003.zip, SHA-256 9765536f274f3b3e35922b29564ac67afc7cfe979df5d8f3cf5f2a3b3649ebc2, matching the release's Network_Probe-SHA256SUMS-01.000.003.txt). It's one of the project's OpenJDK 25 probe apps, like PPSA99869 in #5501: same 290 imports and the same bundled sce_module/libc.prx. The release reports all of its stages passing on a PS5 (firmware 13.60).

What is shown

Its menu. The second row creates the VM (JNI_CreateJavaVM returned 0). The third runs Network25.main: security configuration, numeric IPv4 loopback, TCP client/server echo and UDP two-way datagrams pass, and the NIO stage stops the title:

STAGE: Network: NIO channels and selector
what():  kevent: EVFILT_READ on a non-socket descriptor not implemented

HotSpot warns Attempt to allocate stack guard pages failed at start-up (an anonymous MAP_FIXED mmap gets EOPNOTSUPP); it isn't fatal. Only the controller was used; audio wasn't checked.

Current blocker

kevent: EVFILT_READ on a non-socket descriptor not implemented: the JDK's kqueue selector registering the read end of its wake-up pipe. #5973 fixes it; with it, the third row ends with STAGE: Network25 returned normally and the fourth with STAGE: DestroyJavaVM complete. The PRs it needed to load and start its VM (#5502, #5563, #5643, #5666, #5187) are merged.

How it was run

relinker --windows --to-intel --trap-sdk-syscall-stubs --registry eboot.elf app.exe on the unwrapped eboot.bin and sce_module/libc.prx. The rows were driven with APS5_PAD_INPUT_FILE and tools/pad_input.py (down, cross); the first press after start-up is ignored. The title writes its stages to /download0/java25-startup.log.
