Hi Max,<div><br></div><div>quick guess: "CurrentReadOnlySouceFiles" is a subclass of "Exception". There was a discussion about it last year on this list. So, if you catch too many exceptions in head-less mode (?), you cannot access the source code for a "CompiledMethod" anymore.</div><div><br></div><div>Best,</div><div>Marcel</div><div class="mb_sig"></div><blockquote class="history_container" type="cite" style="border-left-style:solid;border-width:1px; margin-top:20px; margin-left:0px;padding-left:10px;">
