[Bluej-discuss] Do people use BlueJ under Win98?

[Daniel Dekany]

So, nobody uses it under Win98? Sad, I liked BlueJ as an educational
"IDE", and I can't use it on the Win98 machines. Any alternative
exists? Simple, lightweight "IDE" with compilation and debugging
support? I didn't found anything useful yet...

BTW, I looked into this issue a bit more in the case of toggling a
breakpoint, and I have found that it's the
JdiDebugger.toggleBreakpoint(...) call that blocks. Sure, not a big
surprise... The problems is probably around the communication of the
development VM and the debug VM.
