Error description
Error Message: Exception in thread \'_CouplerThread-9229 (stderr)\' java.lang.NullPointerException at org.python.compiler.ProxyMaker.findPython(ProxyMaker.java:72) at org.python.proxies.subprocess$_CouplerThread$1.run(Unknown Source) . Stack Trace: N/A .
Local fix
TR_disableFindRelevantAssumptions=1
Problem summary
Problem is specific to realtime. This happens due to the functionality of finding relevant assumptions at the beginning of the classunloading hook, deattach rest for shorter gc pause time, and reattach back at the end of the hook (end of gc cycle). This doesn't work for RT because the gc yields to the application during the gc cycle. Thus the application may search the assumption and not find them (as they were deattached), causing wrong behavior (in the failing case it was methodOverrideAssumption)
Problem conclusion
This defect will be fixed in: 7.0.0 SR1 6.0.1 SR2 WRT-V3 SR1 . The solution was under metronome, to search also at the deattached list if exist. This was if the assumption exist, we would find it in one of the lists.
Temporary fix
