[Pljava-dev] java.sql.SQLException: An attempt was made to call a PostgreSQL backend function while main thread was not in the JVM

[Petr Michálek]

Hi!

I am repeatedly calling SQL function, and trigger function fired by 
"UPDATE" in sql function crashes with folowing exception. Crash is 
reliable after 100 calls.

java.sql.SQLException: ERROR: java.sql.SQLException: An attempt was made 
to call a PostgreSQL backend function while main thread was not in the JVM
org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:1130) 
org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:933)
org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:139)
org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:346)
org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2Statement.java:294)
org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:285)

Exception is generated by native method in class 
org.postgresql.pljava.internal.TriggerData function

	public boolean isFiredAfter() throws SQLException
	{
		synchronized(Backend.THREADLOCK)
		{
 >>>			return this._isFiredAfter();
		}
	}


Does anybody knows, what is wrong?
