RamUsageEstimator fails with ClassNotFound about orika

[elaatifi]

This should be disabled by default, should be enabled only for troubleshooting (as it impacts also the performance)

But I agree with you on the exception part.

[leonard84]

valueOf(getProperty(DUMP_STATE_ON_EXCEPTION, "true")) is enabled by default at the moment

[elaatifi]

Yes and actually is another issue (in addition to the issue you raised) !

There's a way to replicate this exception?

[elaatifi]

I think the best thing todo is to disabled it by default.
valueOf(getProperty(DUMP_STATE_ON_EXCEPTION, "true")), default value should be "false"

[ndr-brt]

I did the pull request, I think now this issue can be closed until a way to replicate it.

[markthegrea]

This is still happening in our production environment and nowhere else.

java.lang.ClassNotFoundException: javax.transaction.TransactionManager

Is this a mapping problem or is the changing the setting above a "fix"? And HOW do you make that setting change?

Has this been fixed with the new 1.5 upgrades? We are using 1.4.6

[elaatifi]

This happen only when there is already an exception even for previous release. But has been disabled by default in 1.5.

You can also disabled for previous release by adding -Dma.glasnost.orika.dumpStateOnException=false to JVM parameters
