> h2. Problem
> When a typed {{exchange.getProperty(name, Class)}} is called and the stored value requires type conversion, {{ExchangeHelper.convertToType()}} calls {{exchange.getContext().getTypeConverter().convertTo(...)}}. If {{getTypeConverter()}} returns {{null}} (e.g. during CamelContext shutdown, OSGi bundle refresh, or context not fully initialized), a bare {{NullPointerException}} is thrown with no actionable message.
> h2. Stack Trace
> {noformat}
> java.lang.NullPointerException: Cannot invoke "org.apache.camel.TypeConverter.convertTo(java.lang.Class, org.apache.camel.Exchange, Object)"
>     because the return value of "org.apache.camel.CamelContext.getTypeConverter()" is null
>     at org.apache.camel.support.ExchangeHelper.convertToType(ExchangeHelper.java:261)
>     at org.apache.camel.support.AbstractExchange.getProperty(AbstractExchange.java:321)

> {noformat}
> h2. Fix
> Add null guards in both methods, throwing a descriptive {{IllegalStateException}} instead of bare NPE.
