package/openjdk: new package OpenJDK is a free and open-source implementation of the Java Platform. This package provides the option to build a client or a server JVM interpreter. The default option is the server option, as that is what the majority of users use. This JVM interpreter loads more slowly, putting more effort into JIT compilations to yield higher performance. Unlike most autotools packages, OpenJDK is exceptionally different and has many quirks, some of which are below: - X11, alsa, and cups are required to build Java, even if it's a headless build. See http://hg.openjdk.java.net/jdk10/jdk10/raw-file/tip/common/doc/building.html#external-library-requirements for more information. - host-zip is needed for the zip executable. - There is no autogen.sh file, instead, a user must call "./configure autogen." - OpenJDK ignores some variables unless passed via the environment. These variables are: PATH, LD, CC, CXX, and CPP. - OpenJDK defaults ld to the ld binary but passes -Xlinker and -z as arguments during the linking process, which causes linking failures. To fix this issue, ld is set to gcc. - Make -jn is unsupported. Instead, one must use the "--with-jobs=" configure option, and use $(MAKE1).

Install the full JDK instead of just the run time.
The full JDK includes several packages used for debugging and
development. Some useful tools included with the JDK are:
- javaws
Command line tool for launching Java Web Start and setting
various options.
- jcmd:
JVM Diagnostic Commands tool: Sends diagnostic command
requests to a running Java Virtual Machine.
- jinfo
Configuration Info for Java: Prints configuration
information for a given process or core file or a remote
debug server.
- jmap
Memory Map for Java: Prints shared object memory maps or
heap memory details of a given process or core file or a
remote debug server.
- jsadebugd
Serviceability Agent Debug Daemon for Java: Attaches to a
process or core file and acts as a debug server.
- jstack
Stack Trace for Java - Prints a stack trace of threads for
a given process or core file or remote debug server.
- jstat
JVM Statistics Monitoring Tool: Attaches to an
instrumented HotSpot Java virtual machine and collects and
logs performance statistics as specified by the command
line options.
- jstatd
JVM jstat Daemon - Launches an RMI server application that
monitors for the creation and termination of instrumented
HotSpot Java virtual machines and provides an interface to
allow remote monitoring tools to attach to Java virtual
machines running on the local system.
Note:
While the JDK also comes with several tools which can be used
for developing java applications on a target, Buildroot does
not support development on a target. Building the full JDK is
supported for debugging purposes only.
Selecting this option increases the file system by
approximately 110M.
