Platform table is corrupt. Invalid compiler spec ${compilerS

Error message

Platform table is corrupt. Invalid compiler spec ${compilerSpec}

What it means

After resolving the language in fresh(), the code fetches the compiler spec by stored ID via getLanguage().getCompilerSpecByID(cSpecID); if null it throws IOException("Platform table is corrupt. Invalid compiler spec"). The stored cspec ID does not exist in the resolved language's compiler-spec set.

Solutions

1. Use the language version that still defines that compiler spec.
2. Re-install the matching processor module version.
3. Rebuild the trace/platform if the cspec is genuinely unavailable.

// ensure the compiler spec exists in the resolved language
if (language.getCompilerSpecByID(new CompilerSpecID(cspecId)) == null) {
    // use a language version that still defines this cspec
}

try { trace.open(...); }
catch (IOException e) {
    if (e.getMessage().contains("Invalid compiler spec")) { /* require matching language version */ }
    else throw e;
}

When it happens

Trigger: Opening a trace with a language version whose compiler spec was removed or renamed, leaving cSpecID orphaned; corrupt row holding an invalid spec ID.

Common situations: Language pack version drift; cross-version trace sharing where cspec identifiers changed; partially upgraded DB.
