Hello,

The current bytecode limited the size of jumps.

This means that you will get this error if your mehthods are so complex that they
require a jump too large.

Solution: refactor to simplify.

We should improve the error message to explain that.

(this will not happen anymore when the new bytecode set gets adopted).

Forgive me being pedantic, but it will simply be much less likely.�� The limit is raised to +/- 32k bytes, but one can still construct methods that will hit these limits.

Hi,

Sometimes (and also today) after formatting and saving a method, an Error is
thrown.
Following a chunk of PharoDebug.log

TIA
