Dukascopy Bank ver. 2.26.6 / JForex API ver. 2.9.0.1 - Historical Tester -> onStart()

During routine use of the historical tester, stopping and starting a strategy that opens 6 charts (context.openChart(fd)) causes a DEADLOCK
involving the "StrategyRunner Thread" and the "AWT-EventQueue-0" thread.

Have had to issue kill -9 PID over 20 times in the last 24 hours accommodating this re-occuring issue.

Thread Dump (kill -3 PID) below for your information:
Found one Java-level deadlock:
=============================
"StrategyRunner Thread":
  waiting to lock monitor 0x00007f6a3c136b78 (object 0x00000007827cb3e0, a java.awt.Component$AWTTreeLock),
  which is held by "AWT-EventQueue-0"
"AWT-EventQueue-0":
  waiting to lock monitor 0x000000000184ad80 (object 0x00000007833cfcd8, a java.lang.Class),
  which is held by "StrategyRunner Thread"
