What is an "Xdebug server"? If you are talking about spawning LO's
soffice process from a Java process, a problem I could imagine is
that the Java process sets DYLD_LIBRARY_PATH (or maybe some other
env var) in a way that tricks LO into finding a different Java
installation than it would normally do. (This was a known problem
with some versions of Sun's Java on Linux, where the LD_LIBRARY_PATH
problem is mitigated by LO's javaldx helper program run from the
soffice shell script. I'm not sure whether that problem persists in
recent Oracle Java versions or has meanwhile been fixed.)
Oracle Java provides a way to debug the JVM externally as described:

-

Ah, got you now (initially when reading "Xdebug" in the context of
macOS, I thought you were referring to something related to Xcode).
I can reproduce that problem, LO produces
JDWP exit error AGENT_ERROR_ILLEGAL_ARGUMENT(202): saveGlobalRef obj [util.c:60]
FATAL ERROR in native method: JDWP saveGlobalRef obj,
jvmtiError=AGENT_ERROR_ILLEGAL_ARGUMENT(202)
JavaVM: JNI_CreateJavaVM called os::abort(), caught by abort_handler in
javavm.cxx
[Java framework] sunjavaplugin.dylibCan not create JavaVirtualMachine, abort
handler was called.
on stdout/stderr (where the first two lines are from whatever happens
inside the JNI Invocation API's JNI_CrateJavaVM, while the last two are
from LO itself).
This is with Oracle's JDK 1.8.0_121 on macOS 10.12.3, and a simple
command-line invocation of
java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000 Test
with a trivial Test class succeeds, so it smells like there is a problem
in that JDK's Invocation API implementation. I'll dig further...
