Call Java programs from Julia.

Documentation is available at http://juliainterop.github.io/JavaCall.jl

• 0.7 branch is currently being maintained for bug fixes only.
• master branch is currently proposed to be v0.8.0.

JavaCall and its derivatives do not work correctly on Julia 1.1 and Julia 1.2. On Julia 1.3, please set the environment variable JULIA_COPY_STACKS. On 1.1 and 1.2, and on 1.3 without JULIA_COPY_STACKS set, you may see segfaults or incorrect results. This is typically due to stack corruption. The Julia 1.0.x continues to work correctly as before.

For Julia pre-1.5, consider the RootTaskRepl.jl package. With RootTaskREPL.jl, JavaCall is able to execute fine without the need of JULIA_COPY_STACKS=1 with the exception of @async calls. Starting with the Julia 1.5, the REPL backend now runs on the root Task by default.

Do not set the environmental variable JULIA_COPY_STACKS. To use jcall with @async start Julia in the following way:

$ julia -i -e "using JavaCall; JavaCall.init()"
