The property `cnd.tmpbase` comes from pre-`Apache` releases (see [this](https://bz.apache.org/netbeans/show_bug.cgi?id=216366) and [its introduction](http://source.apidesign.org/hg/netbeans/releases/rev/469aedac842d) and [that](https://bz.apache.org/netbeans/show_bug.cgi?id=225920)); so reliance on it is admissible on `*nix` hosts. In fact, its value is still tested, if defined, _otherwise_ `java.io.tmpdir` is tried, while host-related information is being collected in order to create a [`HostInfo`](https://github.com/apache/netbeans/blob/master/ide/dlight.nativeexecution/src/org/netbeans/modules/nativeexecution/api/HostInfo.java) instance. See [`UnixHostInfoProvider`](https://github.com/apache/netbeans/blob/master/ide/dlight.nativeexecution/src/org/netbeans/modules/nativeexecution/support/hostinfo/impl/UnixHostInfoProvider.java), a member of an `Apache NetBeans` 14 module `org.netbeans.modules.dlight.nativeexecution`. It could be corroborated as follows. Launch `Apache NetBeans` 14 with these defined properties: `-J-Dnativeexecution.support.logger.level=0` `-J-Dcnd.tmpbase=/dev/null` `-J-Djava.io.tmpdir=/path/to/new/dir` (Substitute the actual path to the newly-created directory for `/path/to/new/dir`.) Go Window -> IDE Tools -> Terminal Expect the following Error [notification](https://github.com/apache/netbeans/blob/master/ide/dlight.nativeexecution/src/org/netbeans/modules/nativeexecution/support/hostinfo/impl/Bundle.properties): > Failed to use /dev/null as a temporary directory on localhost. > Please, run IDE with -J-Dcnd.tmpbase="other base location" flag to specify > a directory on a remote host where you have enough space and write and execute permissions. (However, `netbeans/ide/bin/nativeexecution/hostinfo.sh` would still fall back to probe `/tmp` and try to make a few ``/tmp/dlight_`logname`*`` directories.) ------------------------------------------------------------ Looking at diffs for `NativeLibraryLoader` of [`junixsocket`](https://github.com/kohlschutter/junixsocket), version `2.2.1` and version `2.4.0`, there are [_no_ changes](https://github.com/kohlschutter/junixsocket/compare/junixsocket-parent-2.2.1...junixsocket-parent-2.4.0#diff-72a326e132770acdb4cc0a74ed76a24961962a984e03eb3e31b67b4ea4e6ce0a) touching `org.newsclub.net.unix.library.tmpdir`. ------------------------------------------------------------ Looking at the history of [`jsch`](https://github.com/mwiede/jsch) in general, curiously, the project acquired an _optional_ dependency on `junixsocket` near the [`jsch-0.1.66`](https://github.com/mwiede/jsch/commit/90a711bfe533e8b483a6617b37f5a9fbd1204820#diff-cbb4d01f335561954103058449dab5622c438352af2477cf0d797cf1a7ff4a82) tagged release, which falls within for [transition](https://github.com/apache/netbeans/commit/13458c81591a3e0551af8eb28f271de9fbba9777) of this project from `jsch-0.1.55` to `jsch-0.1.72`. Methods of [`JUnixSocketFactory`](https://github.com/mwiede/jsch/blob/8251681e6b87a102f512e00ae5b698e54d6f80d7/src/main/java/com/jcraft/jsch/JUnixSocketFactory.java) fire up a chain of constructors and class initialisation for `junixsocket` classes: `AFUNIXSocketAddress` -> `AFSocketAddress` -> `NativeUnixSocket` -> `NativeLibraryLoader`. Now look closely at the top frames in stack traces above. -- This is an automated message from the Apache Git Service.
