Can't start Lua Development Tools

I cannot start ldt.exe (for Lua 5.1) on Windows 10 because I get the following error log. I have no choice about the version of Lua because I am writing an add-on for a game, and that is the baked-in Lua version. This IDE worked well before, but I had to reinstall it at a different location following a disk crash. I know virtually nothing about Eclipse, and not too much about Java (I just want to run Java programs, not write or debug them), so I don't even know if the log extract presented below is helpful.

I see the most likely candidate for a problem is what the log calls problematic frame: jvm.dll. Only difficulty with that is that there are 17 copies of jvm.dll on my machine, and judging by file sizes, about 7 distinct versions, all installed by respectable Java-based applications, such as PyCharm. I don't think this is quite what was meant by "write once, run everywhere".

I have installed both LDT and Java afresh, since that seemed the obvious thing to do. Beyond that, any pointers?
